The definitive guide to running (MS-)DOS (80x86) programs under Windows Mobile

MS-DOS, which was the most widely known operating system of the pre-Windows times on the IBM PC platform, has several unique software titles either not available on other platforms or of considerably better quality than on other platforms. This means emulating MS-DOS, in cases, may be either the only or the best way to get a particular title, let it be an application or a game, run on your Windows Mobile (WM for short) handheld.
In this article, you’ll find ALL (and I certainly mean this!) information you’ll ever need to successfully select and use an MS-DOS emulator.
(Note that, in this article, I refer to all DOS operating systems of the IBM PC as “MS-DOS”. Naturally, the discussion also applies to DR-DOS and PC-DOS and, in this roundup & tutorial, instead of elaborating on the basic operating system itself, I mostly concentrate on the most important aspect of these operating systems: running third-party applications and games.)
1.1 Why an article on MS-DOS emulators?
there are no similar all-in-one articles, let alone in-depth ones. The very few articles ever written on the subject only discuss one of the (several) available emulators, PocketDOS.
the majority of current emulators, particularly the most recommended DOSBox port by n0p, HEAVILY lack any kind of a decent tutorial. In here, you will find all the information you'll ever need configuring and running these titles.
there are many different emulator versions from a lot of developers; this may make the life of a newbie to MS-DOS emulation VERY hard.
Windows Mobile forums are FULL of contradicting and plain bad, unreliable information on these emulators. Someone had to, finally, get the facts straight.
the BEST MS-DOS emulator (that of n0p), being of Russian origin, is mostly discussed in Russian language forums. As one of the several languages I speak is Russian, I understand what is discussed there. That is, in this article, I also build on the information found in Russian forums, making it unnecessary for my readers to suffer from the Babelfish “translation”. To a lesser degree, I've also found some useful user reports & tips in German (which I also speak) forums; I’ve also incorporated the info found there in this tutorial & roundup.
my old, related article (Another reason to get a VGA device – running Legend Entertainment's old adventures reviewed) is heavily outdated because of the brand new DOSBox ports
as the Nominations Manager at Smartphone and Pocket PC Magazine, I have to know everything about Windows Mobile apps. This article also shows I do
1.2 Why should you bother?
As has already been pointed out in the introduction, MS-DOS has several quality titles either not available on other (with a usable WM emulator) platforms or the quality of these titles on all other platforms (again, with emulators) are clearly inferior to that of the MS-DOS version. For example, the evergreen games by Legend Entertainment is a very good example of these (they haven’t ever been released for other platforms). If you don’t know what these games are but you like text-based, high-quality adventures, make sure you give them a try – they’re certainly worth it. And the list of excellent, MS-DOS only titles continues; for example, Betrayal at Krondor was also a PC-only release. This means MS-DOS was a VERY strong gaming platform in the early 1990’s with tons of high-quality or unique titles worth playing even today.
However, in other cases, MS-DOS emulation is NOT something you should always prefer to emulating other platforms or looking for native WM (re)implementations / ports of the same game. For example, as far as games are concerned, with games that only had an MS-DOS version, there may be better emulators (most importantly, "partial" interpreters "only" running a specific type of games; most importantly, from a given game publisher) to run the game than a fully-fledged, full MS-DOS emulator. In addition, some (not many) classic titles have their own WM implementations / ports; examples of these include UFO (the reimplementation is Pocket UFO; see my quick review HERE and the PocketGamer thread HERE), Civilization (Pocket Humanity; unfortunately, FreeCiv has no direct port; PocketCiv only runs on Linux-based handhelds), Pipe Dream (having several WM reimplementation; see for example the Roundup of All Pocket PC Games Part I for some of them), Doom (DoomPPC / DoomGL ES are excellent), Wolfeinstein 3D (see pocketinsanity’s port) etc.
Note that the (vast?) majority of MS-DOS emulator users use emulators for gaming (it’s mostly games that haven’t been released on other platforms or are unplayable / far more awkward to play in emulators); therefore, in this article, I also concentrate on gaming issues. This, however, doesn’t mean you will be unable to make use of it if you, for example, plan to run your old MS-DOS-based apps.

1.2.1 Cases you will NOT want to use an MS-DOS emulator - I: existing ports on other, more Windows Mobile-friendly platforms
For example, if you want to play, say, the infamous Prince of Persia (which doesn't have a direct WM port), I would say you’d better get a NES (Famicom) emulator. The NES version of Prince of Persia is very similar to that of the PC; however, the NES version in no way requires as much resources (including battery power) as the MS-DOS one. Please see THIS for a complete review of NES emulation.
The same stands for, say, Xenon 2 or Risky Woods. Running them in a Sega Mega Drive / Genesis emulator is a much better choice than ding the same in an MS-DOS emulator. The Sega Mega Drive / Genesis emulators require less resources, have better sound (particularly with Xenon 2, which, on the IBM PC, only had speaker sound), are easier to control and produce higher frame rates (just as with NES and Price of Persia) than the current MS-DOS emulators. See THIS for a complete explanation.
These are not hard-and-fast rules. That is, it can't be stated "whenever a port of a game exists on a better-emulated platform, stick to it and forget MS-DOS emulation entirely". When selecting an original platform and an emulator to play a given title, you may want to prefer other, better-emulated platforms for action games like the above. For mouse (stylus)-based, generally, adventure and strategy games, on the other hand, you may want to prefer MS-DOS emulation. For example, compare the following two screenshots, showing Sierra's King's Quest 5 on a(n emulated) VGA PC (running the VGA version of the game) and on the NES (Famicom):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The difference in the visual quality is staggering, isn't it? And, the better visuals are just part of why the MS-DOS version is much more worth playing. The NES' not having analogue / mouse-like input, its cursor needs to be controlled by a (digital) D-pad. This means it's REALLY hard to control the game with the D-pad only.
Incidentally, the same stands for games running on other (mouseless console) platforms like the GBA version of X-COM. These kinds of games should be played under an MS-DOS emulator because they allow for stylus usage, unlike GBA emulators.
1.2.2 Cases you will NOT want to use an MS-DOS emulator - II: existing interpreters for a given game
As has already been pointed out, a specific subset of MS-DOS games have so-called 'interpeters', which run the games without emulating a full MS-DOS environment. This may be advantageous in many respects:
as they only need to run the game (and not an emulated operating system), they, generally, consume far less CPU cycles (and, therefore, both run flawlessly on slower and/or underclocked machines and result in a decent battery life). A well-known example of this is the Magnetic Scrolls interpreter (see review & tutorial HERE), which runs old, freely and legally (!) available Magnetic Scrolls textual adventures in a really CPU- (and, consequently, battery-) friendly way.
they, in cases, are much better integrated into the operating system. Again, an great example of this is the Magnetic Scrolls interpreter. It uses a standard text area (with some extras; for example, automatic text expansion of highlighted text) and standard, relocatable picture boxes. This also means it's, for example, possible to copy some of the text onto the clipboard. What is more, these operating system-level components are compatible with all kinds of operating system versions and configurations. This isn't always the case - let me point out that, for example, (W)VGA and square screens are not supported by many emulators (including, unfortunately, the most recommended one by n0p). Now, compare the quality of the rendering of the in-game text when done by the Magnetic Scrolls interpreter and n0p's MS-DOS emulator (not supporting (W)VGA screens). Yes, the difference is enormous - the interpreter-based version is perfectly playable even on a square-screen or a low-resolution (QVGA) device, while the original MS-DOS game rendered by n0p's emulator is fully unplayable on any Windows Mobile devices because of the emulator's not supporting high-resolution screens, while the games itself used EGA high-resolution.
Of course, it's not only the Magnetic Scrolls games that should be played in the related interpreter, but also a lot of other titles. For example, the earliest Sierra games should all be played under PocketSarien (review & tutorial HERE); most of the Lucasfilm games run better under PocketScumm than under MS-DOS emulators and so on.
There are exceptions, though; the most important being FreeSCI, the interpreter of (early) Sierra SCI games (released in 1989 and 1990). This is so uselessly slow that you will want to prefer an MS-DOS emulator to playing them under FreeSCI. (See THIS for more info.)

1.2.3 Cases you will NOT want to use an MS-DOS emulator - III: existing, native ports available for WM
It’s always preferable to play native WM ports / versions over emulating (if the quality of the port is at least comparable to that of the original running in a high-quality emulator), mostly because of CPU usage and hardware requirement issues. An emulator generally requires (unless we’re speaking of for example BitBank’s SmartGear, which has really modest hardware requirements) a far more powerful hardware than a native game. This means (most and, with emulating MS-DOS, all) emulators are either hard (at least without excessive overclocking) to run on slower devices at a usable speed or, on faster devices, they result in a very quick battery consumption because of the high processor usage.
Now that we’ve seen the cases where using MS-DOS emulators is NOT recommended, we can return to the original subject: running titles that are worth running under MS-DOS emulators because there isn’t another way of making them work.
Let’s see how you can acquire MS-DOS apps (if you don’t have the ones you’d like to play around) and, then, move on to introducing the (current) emulators.
1.3 Getting MS-DOS games
Start with the Wiki page List of commercial games released as freeware. Make sure you get games released before 1994 (or, if you can stand the increased slowness, 1995).
I am not allowed to provide you direct (!) links to so-called 'abandonware' sites. However, if you just use Google, you will find them at once. Also, if you spend more than five minutes at browsing Vogons, the highly useful DOS emulation page, you'll find thousands of links to these sites (it seems some people and even official forums don't take down abandonware links. However, I still refrain from giving you generic URL's, just to be on the safe side.)
Don't be afraid of dowloading from well-known abandonware sites. If you really are afraid of viruses, make sure you don't run these titles directly on your desktop PC, only under an emulator. Then, even if it, for example, formats your (virtual) hard drive (that is, the directory you give it as a hard drive), the damage will be limited. And, rest assured, it won't do any harm to your device. For this test, I've downloaded the games from abandonware sites so that I can test the games they host for viruses and trojans. I haven't found anything. That is, you can absolutely safely download from these sites.
1.4 What can I run?
Generally, games (and, of course, apps) released before 2004. Try NOT to play 3D games (this also includes classics like Betrayal at Krondor - they won't be very fast). You can have success with later, not very graphics-intensive games (for example, adventures).
1.5 Can I run Windows XP on my Windows Mobile device?
Nope. Under the most recommended emulators (n0p's DOSBox port and PocketDOS), all you can do is run Windows 3.11 if you want. I, however, don’t really recommend It - it's the best to stick to emulating strictly MS-DOS applications and games.
With Mamaich's (old) Windows Mobile port of Bochs (Bochs is a full x86 emulator, not just an MS-DOS one), however, you can even install Windows 95 as is described in THIS very long thread (also linked from PPCT). (You'll also need this Nano98 and this micro95 (also see THIS and THIS) tutorials for ripping Windows 95 and 98. Also see THIS for more info.) You, however, won't be able to do anything productive with these installs: it's REALLY slow and has major problems with input devices. That is, don’t even bother reading through these threads – not even the basic operating system will run flawlessly, let alone apps / games. Don’t even think of running for example Starcraft on a Windows Mobile handheld.
2. Desktop MS-DOS / x86 emulators and their ports on Windows Mobile
For the desktop operating systems, there exist several MS-DOS and x86 emulators. Gaming-wise, the ones discussed at Vogons are the most recommended; of them, only DOSBox has Windows Mobile ports. Actually, it has several ports; of them, n0p's port is the most important.
As far as emulating the entire hardware is concerned (also meaning the ability to run, say, Windows XP on a sufficiently powerful, high-class machine - definitely NOT a current Windows Mobile one!), the above-introduced Bochs should be mentioned. In addition, the same Mamaich has also ported QEMU, a very fast (on a current 624 MHz Windows Mobile device, it equals to about a 16 MHz 386 (screenshot 1, 2). Also see THIS.) CPU emulator. It, however, is buggy and has major problems; definitely NOT recommended for ANY serious work. (This is why I've also put it, along with the Bochs port, into the 'not recommended' section.)
In the following section, I elaborate on all the emulators available on WM.

Recommended MS-DOS emulators
2.1 n0p's DOSBox port (current version: 0.63)
As has already been stated, this emulator is the most recommended generic MS-DOS emulator. It's way faster than any other DOSBox port. Its only problems are the following:
the complete lack of support for high-resolution (for example, VGA) devices
being a heavily simplified version of the desktop counterpart, it doesn't support various goodies like MIDI sound (which is way better than the FM synthesizer-based AdLib cards) or emulated modem via Internet / LAN connections for multiplayer (or generic communication).
It, on the other hand, is VERY fast and has a lot of goodies none of the other Windows Mobile DOSBox ports can boast of:
SPEED!
Automatic cycles setting, always providing the best compromise (no need to manually set the cycles)
Very good AdLib / SoundBlaster (SB) emulation
Transparent software input panel (SIP)
It's based on DOSBox version 0.63, which isn't the latest DOSBox version; it's still definitely newer than 0.61, on which some other (not recommended) DOSBox ports are based on (including n0p's own old 0.61 port and that of Mamaich).
n0p is Russian and mostly contributes to Russian forums. Currently, he doesn't plan to update his port to 0.70 (the, currently, latest-and-greatest desktop DOSBox version). It's highly unlikely he will release a version with VGA support either. I'll try to convince him to visit English language forums too so that non-Russian speakers can also speak to him and maybe convince him to develop his emulator further.
2.1.1 Major differences between the original (desktop) and the Windows Mobile versions
While the emulation core is here, n0p’s port (as with other WM ports) lack several ‘goodies’. One of them is MPU-401 (for example, MT32) emulation (see for example the difference between AdLib and MT32 with the infamous game Spellcasting 101: start the game as S101 MT32 2 330 and compare it to the case of running SB-SOUND.COM /b24 and starting S101 without parameters. Also see THIS, THIS and THIS).
Another is connectivity for, say, multiplayer games like F29 Retaliator or Populous (also see: Directserial and Modem Guide; DosBox Guide to Multiplayer Games). While in the desktop version everything is supported (IPX over net; modem and direct serial emulation), in n0p’s version, modem emulation is surely not supported (I’ve thoroughly tested with both F29 Retaliator and Populous); I don’t think IPX is, either. I haven’t tested direct serial connections.
Finally, other goodies like making screenshots of the current screen or capturing WAV / MIDI files are also impossible with the mobile version.
The mobile version, on the other hand, has automatic cycles setting. This isn’t really needed on the desktop (where the CPU, with current PC’s, is powerful enough to run anything “old” at the highest cycles available); on current Windows Mobile devices, however, is a godsend.
2.1.2 Usage
First, download either the XScale or the more generic ARM version from the download page. Uncompress it with (if you aren’t using for example Total Commander) WinRAR to anywhere on your WM handheld (including storage cards). Start dosbox.exe (you can also create a link to it into \Windows\Start Menu\Programs or one of its subfolders like Games if you want to so that you can start it without having to use a file explorer tool).
After starting the emulator, you’ll see something like this (showing the mount command listed at the end of the original configuration file didn’t work):
Now, enter the “mount c "\Storage Card"” command, where change “Storage card” to the name of your storage card (for example, “CF Card” or “SD Card”) if it’s named so as in, say,
mount c "\SD card"
Then, enter the
c:
command to change to the now-mounted virtual drive. Then, by using the “cd” (Change Directory) command, you can step into any directory to execute any programs in there by just entering its name – as was the case with the “real” MS-DOS.
You will also want to include the two commands (or, more precisely, change the “mount c "\cf card\drive"” command already in there) in the dosbox.conf file in the same directory where you’ve unpacked the original, compressed DOSBox distribution. Then, after exiting the emulator (by clicking the exit icon in the upper right corner of the on-screen keyboard) and restarting the emulator. This is shown in this screenshot).
Note that you can also mount virtual CD-ROM's with the same command, by adding the "-t cdrom" parameter. Prefer using the virtual drive D: to mount directories containing the root of the CD file system! Also see THIS (and, with the forthcoming PocketDOS, THIS). An example command:
mount d "\SD card\7thguestCD" -t cdrom
Also note that in order to bring up the full keyboard, you will need to tap the upper left corner of the screen. Then, the keyboard is shown in its entirety (screenshot), part of it transparently (that is, you see what’s under it). Click the corner again to hide the transparent portion. (By the way, this transparency is one of the best features of this emulator). Alternatively, you can also use the “scroll bar” dragging area (screenshot) to quickly drag up and down the keyboard.
2.1.3 dosbox.conf tweaking
If you know the desktop DOSBox version, you may also have heard of its configuration file 'dosbox.conf', already mentioned in the previous section. With the desktop version, you may want to spend some time on learning what the individual parameters are and how they should be configured to achieve the best performance, set up your virtual modem configuration so that you can play for example Populous in multiplayer mode with anyone in the world and so on. (You can find a description of the desktop version HERE).
With n0p's port, most of the parameters that need to be tweaked in the desktop version don't really need to be touched if you want to have better performance. In the desktop version, you may want to spend considerable time testing for example how the OpenGL version of the emulator behaves compared to the normal one. In the WM version, this is not necessary because OpenGL (and other, alternative screen output methods) are simply not supported. This is certainly good in that you don't need to spend any time on fine-tuning the emulator - it'll deliver the best performance "out of the box".
However, there are still some parameters you may need to know of; most probably, the following ones:
core (the most important one - you'll need to edit it if you plan to run 80386+ apps / games)
memsize (if the default three Mbytes of EMS / XMS wouldn't be sufficient. It's only with few titles that it isn't; for example, with Heroes of Might and Magic, which requires 4434 kbytes of XMS / EMS and 374 kbytes of conventional memory)
finally, the autoexec section, where you should put at least mounting in your storage card(s) and changing to there so that you can save you some typing
And, some less important, but still useful parameters:
dpadmouse (if you plan to play a game that doesn't support the other two forms of mouse emulation. There are very few cases you will ever need this.)
hwkeyX and hwkeyX_ma (if you want to redefine what the four hardware keys do and what their effect on the mouse buttons are)

In the chart HERE (sorry, it'd be too big to be included in here - you'll need to click the link), I both explained ALL the parameters in the configuration file of n0p's DOSBox and compared the original desktop version to that of n0p, as far as these parameters are concerned. As you'll see, n0p's version uses the values of only very few of these parameters, unlike the original desktop version. (Actually, in this respect, Wall's approach in his pDOSBox 2b2 is better - he has deleted all the non-supported parameters from the config file, making it much more approachable for anyone not having read my description of what is used and what is not.)
The chart also provides an excellent summary of the meaning of these parameters. This is very important because n0p's original documentation (available HERE) is pretty weak (or straight non-existing) and noone else has ecer published anything comparable, as far as his port is concerned.
2.1.4 n0p's DOSBox 0.61
This highly outdated and slow(ish) version should just be forgotten. Always prefer the latest (0.63) version to it.
2.2 Wall's DOSBox port (current version: 2 beta 2), pDOSBox
(Alternative download with the sources HERE (see the bottom of the page) and here)
This, unfortunately, fully discontinued (also see THIS) emulator has some goodies; most importantly, (W)VGA support. It's therefore highly recommended for (W)VGA users wanting to play high-res (CGA hi-res, EGA and VGA hi-res) games. However, no one else should want to use it on a daily basis - (W)VGA device owners only wanting to play low-res (320*200) CGA / EGA / MCGA / VGA games should stick to n0p's port (introduced above) because of the vastly superior speed, sound support, transparent SIP etc. Note that many state Wall’s pDOSBox is faster (see for example THIS) than n0p's emulator. That's certainly not the case, particularly when it comes to sound emulation.
A tip: as the beta is expired, you'll need to set back the internal clock of your handheld before starting the emulator. For example, if you set back just the year to 2006, it'll work just great.
Another tip: the emulator often crashes upon using backspace when you delete something in a previous command taken out from the DOS history. This means don't use the backspace when in the DOS command line with constructs like "cd somegamename / somegamename", where you try to delete "cd" from before somegamename - it'll most probably lead to a crash.
I'd like to thank Michu (author of the well-known EmuPage - a MUST for every emulator fan!) and AximSite forum members heybhouse and Half Decaf for helping me finding this version.
2.2.1 Using pDOSBox 2 beta 2
After downloading and unpacking, you’ll need to transfer the files (along with the subdirectories) to your handheld (a storage card will do just fine). Start the emulator by starting PDBFEND.EXE. As with n0p’s DOSBox, you’ll want to create a shortcut to this file from your Programs menu; this is also explained in the README.TXT in the same directory.
Using the emulator is pretty much the same as with that of n0p’s DOSBox. You mount a directory (which can also be on a card) with a command like mount c "\SD card", go to the new virtual drive and start your favorite apps.
The emulator has a similar on-screen keyboard (SIP) than n0p’s DOSBox. It, however, isn’t transparent; this also means that, if the DOS prompt is already under the (maximized) SIP, you won’t see anything of it, unlike under n0p’s DOSBox. That is, you won’t see what you write. To quickly fix this problem, issue the ‘cls’ (CLear Screen) command (consisting only three letters, it's easy to be entered even if you don't see the prompt); it’ll clear the screen and the prompt will be shown at the top.
Unfortunately, the keyboard, unlike with n0p’s DOSBox, can’t be maximized by clicking the upper left corner of the screen. The only way to maximize it is pressing the Left arrow on the D-pad, while you can switch between the three panels using the Down arrow. This, unfortunately, also means you can’t use the D-pad in, for example, games.
Finally, another disadvantage of this port is the fact that it doesn’t support automatic emulation optimization – that is, built-in fine-tuning the emulation “strength” based on the CPU load. This also means you will also want to keep an eye on the actual CPU load of the given application / game and, if it has reached 100% and is constantly staying around it (not decreasing under 96-97%), just decrease the cycles given to the emulator. This, when done properly (so that the CPU utilization remains between 90 and 95%, but doesn’t exceed, say, 97%, driving the CPU into saturation and leading to (even more) sound problems and, after a while, visible visual performance degradation) maximizes performance. As games / apps are vastly different in their CPU usage, manually tuning the performance can be a real pain in the back. This is why the auto performance tuning in n0p’s app is a godsend – there, all you need to do is decrease or increase the frameskips, which is far easier and requires far less manual work than the cycle emulation fine-tuning in DOSBox ports not sporting auto settings.
2.2.2 The old pDOSBox 1.1
An earlier, release version of the above-introduced pDOSBox. It is clearly weaker than pDOSBox 2 beta 2. Therefore, I don't recommend it at all, unless you, for some reason, want to prefer it over 2b2: for example because you don’t want to set back the clock all the time.
2.3 PocketDOS 1.12
PocketDOS is the oldest MS-DOS emulator for Windows Mobile. It has been around for quite a while - well before the first DOSBox ports. It was, however, only lately that it became a bit more gaming-friendly; for example, it only received VGA support (including high-resolution modes on high-res Windows Mobile handhelds) in 2004.
Unfortunately, in general, it's less suited for generic gaming than n0p's version. Not only because of the non-existing (and, as far as beeper emulation is concerned, vastly inferior to that of n0p's DOSBox) SoundBlaster / AdLib emulation, but also because, in general, fewer titles run under it. A well-known example of this is Civilization, which, as of the latest, 1.12 version, still refuses to run, unlike under n0p’s DOSBox port.
The latest, 1.12 version of the emulator has just been released. The promised emulation speed increase (when using the built-in core and not enabling the other, 286+ cores) is indeed pretty good and, generally, outperforms even n0p's DOSBox in some games and is indeed faster than the previous, 1.11 version. Also see my Norton System Information benchmarks in the main comparison chart, which clearly shows the new version has indeed become faster. Also, some (minor) bugs have also been fixed; for example, the missing toolbar / SIP keyboard issue on the Dell Axim x51v (see THIS screenshot, taken under the old version).
It has some other goodies too. For example, unlike any of the DOSBox ports on Windows Mobile, it does support physical serial ports and printing. You may find this functionality important if you need to run legacy MS-DOS applications collecting data via the handheld's serial port and/or need to print out some stuff.
Also, another definite advantage of the title is being based on a full DOS operating system. This means for example batch files calling even scarcely used DOS commands, using not widely used command-line parameters, the full DOS operating system will know it. This is what the DOSBox ports are clearly weaker at. Note that you can choose from three versions of different DOS versions (that of Caldera (ex-Digital Research), DataLight and, in addition, the default FreeDOS) upon installing the application as can also be seen in this screenshot. You can even install more than one of them and just switch between them in Settings / System / Startup / Boot from (screenshot) when you need to switch (because, for example, a given application or game doesn’t run under the default FreeDOS. An example of these apps / games is Legend's Spellcasting 201, which doesn't run under the default FreeDOS.)
However, in most cases (when you only want to run some programs / games and don’t want to issue delicate DOS commands or run batch files that do depend on some scarce feature of DOS not present in the DOSBox implementation), being based on a full DOS doesn’t deliver much advantage as most games don't make extensive use of the external DOS commands - not even internal (command.com) ones.

2.3.1 Scaling, resizing
PocketDOS' scaling/stretching behavior in high-resolution modes (on a high-resolution handheld) is vastly different from that of DOSBox ports. DOSBox ports don't give the user any way of deciding how to downscale (make it smaller) the original high-resolution (640*350 EGA or 640*480 VGA) images to fit on a screen with SIP's on them. They only have one default behavior for all the possible resolutions as is described in the following matrix:
PocketDOS, on the other hand, behaves radically differently. It offers the user no less than four scaling options in hi-res EGA and VGA modes; two of these options (the one employing a horizontal compressing by 2, the other also vertically) targeted at users using a QVGA handheld so that they don't end up having to pan horizontally (and, in the second case, vertically), unlike in the cases of using the original resolution (where both horizontal AND vertical panning is necessary and, in many cases (for example the main text area of Legend Entertainment games), not even texts can be read without excessive (in every single row) horizontal scrolling.
(Note that the main comparison chart – to be linked below – has a lot of screenshots demonstrating these modes.)
As can be seen, the way it lets the user to select a scaling mode of his choice and, unlike DOSBox ports, not forcing QVGA users to either a downscaled, non-pannable view of the screen or one that needs to be panned in both directions (but not both) is a big advantage. In this respect, PocketDOS should be the first emulator to be given a try if you plan to play high-resolution games on your low-resolution handheld. Again, when presenting high-resolution originals on low-resolution (320*240) handhelds, it has a decided advantage over DOSBox ports.
Note that one of the video modes employing downscaling of VGA originals results in pretty bad results (particularly when you also enable the on-screen keyboard in addition to the always-visible toolbar). Here, some people (see X-Phile on Sun Jun 12, 2005 11:46 pm) also complain of this. If this issue gets on your nerves, make sure you switch to a non-scaled view, even if it results in a need of (sometimes heavy) vertical panning.
Finally, let me point out that the main comparison / feature chart (to be linked below) has a LOT of example screenshots demonstrating all these modes on both QVGA (low-resolution) and VGA (high-resolution) devices.
2.3.2 Using PocketDOS
Using this application is pretty straightforward. If you have a WM5 device (meaning the lack of, from the, in operating systems prior to WM5, RAM-based separated Built-in Storage (BIS)) with a single storage card, it will be automatically mounted as drive c:. That is, in these cases, after booting in, you will see the contents of your memory card right away and can start running your favorite apps at once, without having to play with manually mounting anything.
If, on the other hand, you either have a handheld with an operating system prior to WM5 with a built-in BIS and/or two memory cards (and you want to access the contents of your CF card, not that of SD), you will need to manually mount the other card. Fortunately, it's pretty well explained in the built-in help of the setdrive command.
You will most probably want to switch to Landscape mode (from the default Portrait) if you can live with the three-row SIP (and you aren't sensitive to the probably bad polarization problems of your handheld, which may be an issue with several non-high-end handhelds like the Dell Axim x50v/x51v). To do this, click the Windows button (above Esc), go to Settings / Display / Orientation and switch orientation.
2.3.3 Problems with the EMS/XMS memory
Unfortunately, PocketDOS has much more problems with the extended / expanded memory than n0p's DOSBox port. You can't allocate so much memory as in the latter and when you do allocate, the entire emulator may still restart itself when you try to start a memory-hungry title. This problem is particularly topical when you use the DOSBox CPU plug-in (and not that of the MUCH slower Bochs).
Also see some related posts in this thread for more info on other limitations of the memory model used by the emulator.
3. Not recommended emulators
In addition to the already-introduced three recommended emulators (and some of the older titles), here's a list of the non-recommended ones:
3.1 Mamaich’s DOSBox port
(Note that n0p’s (old and not recommended) 0.61 DOSBox port is based on this one, with some enhancements)
Shows some black screen and, then, immediately exits.
3.2 Ming Zeng's PocketDosBox v0.1.0
(based on the rather old DOSBox 0.60, last touched March 06, 2005)
Doesn't work on any Windows Mobile test device I've thrown it at (Cannot find … or one of its components)

4. The main comparison chart
Yes, I haven't given up throwing even more information at you This article also contains a VERY large comparison chart available HERE. CLICK THE LINK, YOU WILL FIND THE INFORMATION THERE REALLY USEFUL! Also, as usual, it's packed with screenshots. Also note that this chart has nothing to do with the previously linked dosbox.conf chart - they are completely different entities (yes, this article has a LOT of material!)
In addition to comparing the two DOSBox ports by Wall, the new one from n0p, the latest, just-released PocketDOS and, finally, the desktop DOSBox original, I've also made some extensive, real-world compliance testing with several games and utilities. Feel free to scrutinize these reports. Note that I've preferred checking my favorite titles; hence the several Legend Entertainment games (all of their (text) adventure titles, except for the late and, therefore, CPU/memory-hungry Death Gate and Shannara).
I especially recommend the "Norton System Info benchmarks: effects of different fine-tuned parameters" row to see how the performance of these emulators can be tweaked. As can clearly be seen, the only way to (slightly - but not much!) increase the performance of n0p's application is increasing the frameskip parameter. PocketDOS is more tweakable.
In the same row, I've also elaborated on the effects of enabling 286+ (with PocketDOS) /386+ (with the DOSBox ports) emulation. As can clearly be seen, the speed hit caused by these plug-ins is particularly high with PocketDOS. Try to stay away from the Bochs plug-in - it REALLY slows down the execution! The DOSBox plug-in of PocketDOS is clearly better. Too bad it has severe memory-related problems: the majority of 386+ games I've tested did run with "real" DOSBox ports but refused to start with the DOSBox plug-in of PocketDOS. They, on the other hand, generally ran under the (again, VERY slow) Bochs plug-in.
If you don't understand something in the chart, make sure you also check out the, in Section 2.1.3, already discussed dosbox.conf chart. I've elaborated on a lot of issues in there - for example, what the different mouse emulation modes mean, when they should be used, which games are affected etc.
Appendix A - SI benchmark results
In addition to the "tweaking" benchmarks I've elaborated on in the main chart (again, see the "Norton System Info benchmarks: effects of different fine-tuned parameters" row), I've made some really thorough benchmarks with n0p's DOSBox port to see how the frameskip parameter affects overall speed and what the speed of the different CPU cores are. This has all been measured on my 624 MHz Dell Axim x51v.
As can be seen (and has also been pointed out in the main chart),
it's not really worth using more frameskips than four or five; it won't result in further performance increase
the 'verysimple' core is about 50% faster at every frameskip settings than the full core. Interestingly, the, by n0p, not recommended, 386+-compatible normal / dynamic cores produced better results than the 'full' core. This also means if you need 386+ emulation, you may want to give a try to the 'normal' core first, and only then to the by n0p recommended 'full'.
Note that the tests were done using auto cycle settings. As has already been explained, you will NOT want to disable auto cycles. If you do disable them, you will have a hard time using these kinds of (synthetic) benchmarks to correctly benchmark your emulator. Some examples of this case (using Wall's emulator as an example):
The CPU cycles can be increased infinitively; at 9900 (instead of the, on the x51v, default 2700, where the SI index was supposed to be 16), it displayed an index of ~59. These values remained the same after starting a very CPU-intensive background process (Pocket Controller) to make screenshots. That is, the results are plain wrong.
The frameskip parameter doesn’t seem to have any effect (1 2), which is, of course, incorrect.
Recommended links / additional info
A trip down Memory Lane: PocketDOS and Realms of Arkania. The author asks whether the emulation speed depends on the speed of the medium PocketDOS is installed to / the games are stored on. In general, no; that is, you can keep your stuff on (even slow) memory cards and don't need to copy them into the main storage (let alone RAMDisks under WM5+).

A Russian thread on PocketDOS
Yes, and another one at www.soneric.ru
A German thread on n0p’s emulator, also pretty informative: DosBox für Pocket PC. It also contains a list of games running under n0p's emulator. Note that the original author states installing PocketDOS is very complicated because you need to get a copy of MS-DOS from somewhere. This is certainly not the case: later versions of PocketDOS have all come with MS-DOS built-in; on top of that, it's a free DOS version by default. No need to install anything else - and, if you install PocketDOS using the desktop installer EXE, you only need to run one EXE file and just press the Next buttons. He also states King's Quest 5 and 6 run slow under the emulator with 0.61 - that's not the case with 0.63 any more. Also note that, at first, he found that using the OpenGl value instead of Surface (see the Output parameter) results in slightly increased speed (using on a 400 MHz QVGA Loox). Later, however, he stated he didn't see any difference.

windows 98 emulator – discusses PocketDOS’ (poor) Win emulation capabilities
A possible alternative to pDosBox (with sound) - at first, discusses n0p’s old port; then, switches to the new one.

UPDATE (06/03/2007):
In the meantime, I’ve been notified of a brand new, Wall-based project; pckDOS (current version: 0.63 001). To install it, just download pckDos_063_001.rar, decompress it and transfer the files inside it to anywhere on your PDA. Create a .lnk file to either pckVGA.exe to pck320.exe (for VGA and QVGA devices, respectively).
Unfortunately, it’s clearly worse than Wall’s version 2.0. While it does have VGA support, it’s even slower, has absolutely no sound emulation (not that that of Wall could be called satisfactory) and has no ways of quickly maximizing the SIP when possible (see “Left” on the D-pad with Wall 2.0 or clicking the upper left corner with n0p 0.63). At least the latter is a major problem; so are the traditional problems with Wall’s app (for example, messed-up characters in Legend Entertainment’s EGA games).
It’s very important to start pckDOS using a link; otherwise, you’ll have MAJOR SIP problems as can be seen in here. With Wall’s original 2.0 (or any other app), no such problems exist – that is, with them, you don’t need to put a link to the main executable in your Start menu.
All in all, this title is NOT recommended. Stick with Wall’s version 2 if the need for setting back the clock isn’t a problem because of (mostly) the maximizable SIP.
As far as MS Smartphone-compliance is concerned, the following needs to be known:
* n0p’s DOSBox 0.63 and the QVGA version of pckDOS 0.63 001 don’t even start on any SP platforms
* Wall’s 1.1 starts on QVGA devices (like the Vox) but has severe problems with text input: on the Vox, it’s impossible to enter characters that have a number of their secondary function
* The best is without doubt PocketDOS (tested with version 1.12): it has excellent text input capabilities using the numeric keypad of Smartphones and supports newer, higher-end QVGA devices (in both Portrait and Landscape mode), in addition to the traditional 176*220 screens (screenshots of the latter HERE and HERE - as can be seen, you can't expect much of the old, low-resolution Smartphone screens. Newer QVGA screens are WAY better.)
A screenshot of running the emulator on a new QVGA MS Smartphone (the HTC Vox) in Landscape mode:
(same, showing running Populous HERE)
Of course, it needs a LOT of learning because of the numerous input modes. This is only explained in the in-program help (screenshot) and, it seems, nowhere else. I’ve collected some of them so that you can have some idea how text input / cursor control work.
Main control:
Back Backspace
Esc Escape
Talk Cycle 'zoom' modes
Home Minimise PocketDOS
Vol Up/Down Scroll display left/right
Right Softkey Menu
Left Softkey Switch input modes
Text Mode:
# (Hold): Select symbol
#: Space
* (Hold): Select text entry method
0-9: Text entry
*: Cycle text entry methods
This is about the third of the available modes / controls: there are a lot of others.
I haven’t had any problems with PocketDOS running on newer (QVGA) Smartphones, except for the inability to activate the menu – the right softkey just didn’t work on my HTC Vox (tested both of them). It, on the other hand, worked flawlessly on my older WM5 AKU3 176*220 HTC Oxygen.
As usual, in the meantime, I’ve received a lot of praising for the article; for example, HERE is a sticky request at HowardForums, one of the most lively mobile phone forums by forum regular Ago Vino Verita

The (Java) MIDlet Bible

(Note that this Bible does NOT discuss Java applets or applications. For more info on running applets under Windows Mobile, see the Web Browsing Bible; for application-related info, see my generic Java articles.)
You may have already heard at least of Java games (more precisely, MIDlets) running on almost all current “dumb” phones. These games are all the rage today, especially with teenagers, which also means there are thousands of sometimes really high-quality games for ordinary phones, all written using the portable Java language, ready to be played on (almost) any kind of mobile phone. Just an example: in THIS HowardForums thread, the topic starter post lists some (but not all!) games available for the Samsung QVGA 240x320 phones (d600, d900, e900 etc – not only Windows Mobile ones!). Quite an impressive list, isn’t it? And it’s just the tip of the iceberg – there are a lot more games, all waiting for you to purchase, download and run!
No, don’t think MIDlets are only for gamers and are absolutely useless otherwise. You can make a good use of them in the enterprise too. There are several solutions already for, for example, mobile payment, reservations etc. done using a MIDlet as opposed to the Web, which is, in a lot of cases, is much harder to access / operate on a small-screen device. Controlling for example your bank transfers via SMS can also be less intuitive and/or require a lot more work / data entry than using a GUI to do this. Other, known enterprise-related MIDlets are Jupiter, which is basically a financial data streaming program (also see THIS) and Betfair (also see THIS). Should you be interested in these “MIDlets in the Enterprise” questions, I really recommend Michael Juntao Yuan’s excellent book “Enterprise J2ME: Developing Mobile Java Applications” – I’ve learnt a LOT from it. Highly recommended!
1.1 Microsoft and third party MIDlet manager developers
Unfortunately, Microsoft doesn’t support Java (and its, in this Bible discussed subset, MIDlets) at all. The sole reason for this is the fact that Java is a direct competitor to the .NET (Compact) Framework, and is (also) supported by almost all major competitors of Microsoft; in the telco area, most importantly, Nokia and Sony-Ericsson (S-E), the two major players in producing “consumer”, “entertainment”, “not-strictly-enterprise” handsets.
This, unfortunately, means that, under Windows Mobile, MIDlets are not as widely supported as on competing mobile platforms; most importantly, Symbian. Nokia, S-E and the rest have spent a lot of $$$ on implementing really usable and top-notch MIDlet runner environments (MIDlet managers or KVM’s) in the last few years. Microsoft didn’t do the same, only third-party developers, who, because they considered Windows Mobile not to be a gaming platform, didn’t pay much attention to implementing a very good MIDlet manager on the platform (back then, there were far fewer enterprise / productivity MIDlets than today). Just an example: while the mid-2003 Nokia N-Gage certainly lacked at the MIDlet department (very few current games run on it and if they run – for example, the River Storm chopper simulator -, they are almost unplayably slow, as opposed to current Nokia handsets like the N95), the year 2005 Nokia 6680 already had almost flawless MIDlet support. For example, it even supports Bluetooth, which still (as of late 2007) hasn’t made it to the Windows Mobile MIDlet managers, “thanks” for the third-party, uninterested, unmotivated software developers’ neglecting the platform.
1.2 Is it worth it for gaming?
The lack of Microsoft’s commitment to the decent support of MIDlets, unfortunately, means Windows Mobile users are, generally, in a far direr situation than owners of phones from manufacturers involved in developing Java further and spending a lot of $$$ on making their Java support as good as possible. A perfect example of this is, as has already been stated, Nokia. Nokia’s latest, gaming-enabled, top-of-the-line smartphones (most importantly, the PowerVR 3D-accelerated N95 (-3 / 8GB ), the N93(i) (the jBenchmark page is HERE) and E90; the complete list of current phones, based on their 3D benchmark results, can be found HERE) run truly three-dimensional (and, therefore, hardware accelerated) MIDlets considerably faster and FAR better than anything on Windows Mobile. S-E, with its 3D accelerated, touchscreen Symbian UIQ 3 models like the W950, the P990 and the M600, shouldn’t be forgotten either.

1.2.1 3D support
Currently, I don’t know of any Windows Mobile devices with 3D hardware accelerated Java (MIDlet) graphics. The Aplix folks (developers of Jblend) told me their KVM does support the underlying 3D hardware accelerator. Unfortunately, the (very few) models available outside Japan that it comes with preinstalled do not have 3D acceleration and the (comparatively old) Jblend version available for installing on any device don’t show any kind of 3D acceleration support (I’ve tested this on my 3D accelerated, 2700G-based Dell Axim x51v). Therefore, I’m not really sure it will indeed work with, say, future GoForce 5500 (currently, the O2 XDA Flame and the Toshi G900 has the CPU (neither of them come with Jblend)) and/or the new Qualcomm 7200 chipset, which is to be found in several last-generation HTC and just-announced I-Mate handsets. I don’t think they’ll come with Jblend (why would HTC change their MIDlet manager OEM again, only about a year after switching to Esmertec from the dying TAO?) either. Let’s hope for the best (for example, Esmertec’s (re-)introducing M3G support with support for hardware acceleration into Jbed), though.
The situation, now that – unlike with the 2700G and the GoForce 5500 – the Qualcomm MSM7200 chipset will be a de facto standard in many current- and most next-generation WM phones, will surely change in the future. I’m, however, pretty much sure you won’t see a 3D accelerated MIDlet manager any time soon under Windows Mobile. Again, software developers still consider Windows Mobile a non-gaming platform not really deserving 3D MIDlet acceleration.
What does this all mean? If you’ve got used to the quality of game MIDlets on your favorite Nokia N93(i)/N95/E90 or Sony-Ericsson handsets, you’ll be pretty much disappointed; particularly if you want to run 3D and/or Bluetooth (multiplayer)-based games.
1.2.2 Bluetooth support
Yes, the lack of Bluetooth is another major problem with all current Windows Mobile MIDlet managers. Don’t think of only multiplayer games – there are other uses of Bluetooth used from MIDlets; an example of them is Blooover (a great Bluetooth Sniffer), data exchange over Bluetooth and so on. You can find more information on the latter for example HERE.
Note that, as opposed to what the 4pda.ru folks stated, few games refuse to deploy / run because of the lack of the Bluetooth support. (See the main games compatibility chart for more info on these titles.)
1.2.3 Sound issues
There will be other problems too if you plan to play the HUGE library of MIDlet games available today. The most important of them is the bad sound emulation, which is quite big a problem with some MIDlet managers severely affecting the gaming experience. Actually, currently, it’s only Esmertec’s Jbed that didn’t have any problems playing back ALL the midi music I’ve thrown it at (and, of course, that of Nokia on Symbian); all the other (Windows Mobile) MIDlet managers had a much worse sound. In many cases, the music they produced was very hard to even recognize – in a way, they sounded like for example an SNES emulator running on a not-fast-enough Windows Mobile or Symbian phone.
1.2.4 Control issues
Furthermore, you’ll surely be faced control problems. Depending on the MIDlet manager you use AND the game you’re trying to run, you will face sometimes severe control problems. Either the two softkeys won’t work (not even on Pocket PC’s, where you can also try to use the stylus to “press” them) or the D-pad / Action button, or both. Note that there are some solutions to this problem (particularly if you have a Smartphone (or an, in this regard, similar Pocket PC phone like the Asus A525) with a hardware phonepad). I’ve elaborated on these questions in a separate article HERE (cross-posted to PPCT, AximSite, XDA-Developers - 1, XDA-Developers - 2, XDA-Developers - 3, FirstLoox, BrightHand, HowardForums, SPT, MoDaCo, PocketGamer.org, PocketGaming.de).

1.2.5 Screen size issues
The question of the screen size and MIDlets displayed in full screen mode should also be mentioned. As MIDlets are, generally, written for a multitude of different devices (to maximize revenue and minimize developing costs), they, generally, support three screen resolutions: 176*208 (the traditional Nokia screen size), 176*220 (the traditional Sony-Ericsson screen size which is, incidentally, the same as that of the traditional Windows Mobile Smartphone) and, finally, QVGA (240*320) – the screen size of the latest Nokia / Ericsson handsets and, of course, higher-end MS Smartphones. And, naturally, Pocket PC’s as well, which, in addition, may also have VGA (640*480) or even WVGA (800*480) screens.
MIDlet games come in two flawors: either dynamically stretching themselves to fill in the entire screen estate of the device they run on in-game (while, in most cases, using the least common denominator, that is, 176*208, to display menus), or fixed to a given resolution. Of course, using the former is preferable (when possible) because you will have a great chance of being able to run it on your even WVGA Pocket PC full-screen. Interestingly, the game speed will, in many cases, remain acceptable even at such high resolutions. This was one of the best surprises I’ve encountered during my thorough tests.
As opposed to the, technically, much more superior and mature Nokia MIDlet Manager, Windows Mobile KVM’s aren’t, generally, full-screen, which, unfortunately, mean some 20-25 or even 40-50 pixels at the bottom of MIDlets hard-coded to the QVGA resolution will be not shown on QVGA screens, depending on whether the actual MIDlet manager shows both (top and bottom) screen bars (TAO, IBM J9 or Jeodek M3G on the Smartphone platform) or “only” the top bar (Jeodek M3G on the PPC platform; non- M3G-capable Jeodek on both WM platforms, Jblend). Nevertheless, there will be missing information; in most cases, the softkey labels, but, with many games, also status messages, speedometers and the like. You can find a lot of comparative screenshots in both the previous 3D MIDlet article and the main game compatibility chart. In all these cases (when the missing information does get into your nerves), you will want to try very hard to, first, find a KVM that does full screen (Jbed or, if you can live with the bad or non-existing audio support, the full screen version of Jblend) and if they turn out to be unable to run your title, switch to a MIDlet version written for a device with a smaller screen (for example, the 176*220 version instead of the QVGA one). In the latter case, however, a large part of your screen estate will remain unused.
As far as application programs (Opera Mini, Gmail, Google Maps etc.) are concerned, they all dynamically stretch themselves to make use of the available screen estate; therefore, you won’t have problems with them on any device, with any MIDlet manager.
1.2.6 (Free) alternatives to MIDlet gaming
As several MIDlets are just rewrites of old classics like Bonk, you may find it useful to look around any online console ROM or abandonware game repository for versions of the game you plan to play. In a top-notch emulator like SmartGear, they might run FAR better than ANY MIDlet manager on your particular handset. Make sure you read ALL my previous, emulation-related articles (the Emulator category of my blog is HERE) to see what gaming console platforms there are and how they are emulated by Windows Mobile.
Just an example. The recently released Bonk’s Return runs MUCH slower (and/or using MUCH more battery) on all my test Windows Mobile devices than the same title under a PC Engine emulator like SmartGear.
All in all, if you find a MIDlet that you find a bit on the slow side, make sure you look around on, say, WikiPedia to see whether the game (originally) had handheld / desktop console versions (or, for that matter, a home computer one – even many home computers of the eighties and the early nineties are better emulated than MIDlets, particularly if you can’t use Jbed because of the compatibility issues). If it did, make sure you check out the console version first, under an emulator. Again, it can’t be stressed enough how important it is for you to thoroughly read through my console/computer emulation-related articles so that you know what emulators there are, how the original titles are emulated under Windows Mobile, what platforms to prefer when there are ports to multiple platforms of a given title etc. Yeah, I know you’ll end up having to spend hours to read all those articles, but, if you’re a hardcore gamer, you’ll certainly find it useful.
1.3 Is it worth it for non-gaming?
It definitely is; most importantly, for Web browsing with the brand new Opera Mini 4 (current, recommended version: beta 2) reviewed HERE. Opera Mini 4 is a freaking good and, what is more, FREE Web browser – in many cases, it’s preferable over all the other Web browsing solutions available for Windows Mobile.
There are other productivity MIDlets meant for non-vertical markets too; the most important example of this is the Gmail MIDlet, which offers a very nice alternative to browsing, searching, answering etc. your Gmail mailbox from your handheld, including Windows Mobile ones. It’s WAY better than any Web-based solutions (see the Web Browsing Bible for the why’s) and, given that it allows for using some really advanced functionality (for example, searching) on the server side (this wasn’t available before; now, Gmail has just implemented IMAP access (another, related PPCT thread), which might let do this from a capable IMAP client as well – see my IMAP Bible for more info), it might still be preferable on a device that, otherwise, is properly configured to access Gmail via POP3. You may also want to take a look at THIS, THIS, THIS, THIS and THIS thread / article too.
Note that now that Google has released an excellent, native Windows Mobile version of the client, (as of the current, 1.2.0.13 version) the need for the MIDlet version of Google Maps is decreased. The native version works just great on both WM platforms and is accessible HERE for download as a directly installable CAB file. Note that there may still be cases you will want to prefer the MIDlet (that is, non-native) version of this program; see for example the comments HERE, where user “fixup” complains of the native version’s keeping the backlight and the connection on (as opposed to running the Java version under a MIDlet manager), which both may lead to (vastly) increased battery consumption.
Finally, as you most probably WILL want to run at least Opera Mini (or its modded version) on your device, the answer is YES.

2. Available MIDlet managers
In this chapter, I give you a thorough overview of what current (!) MIDlet environments there are, how they compare to each other and which one you should prefer. As you’ll see, particularly if you’re a power user and/or player, you will want to keep different KVM’s on your Windows Mobile handheld simultaneously so that you can make use of the functionality of each of them (there’s no “best” KVM – unfortunately, the otherwise best Jbed lacks some functionality only provided by other KVM’s).
Note that I don’t provide you download /purchase links here. You can find all of the download sources and / or accessibility remarks in the main chart, in the second, “Price / availability” row.
Also note that this is just a sketchy list of what KVM’s there are and what (dis)advantages they have. For a full list of tips, tricks, capability and problem lists, you MUST consult the above-mentioned main chart. Note that, in Chapter 4, I will also elaborate on the meaning of the rows in the chart.
2.1 Esmertec Jbed
This is by far the best and most recommended KVM for Windows Mobile, (QVGA; NOT 176*220 – on the latter, it refuses running deployed MIDlets) Smartphones and Pocket PC’s alike. Its only problems are the lack of M3G (3D gaming) support and the inability to run more than one MIDlet concurrently. As with the other products of Esmertec, it isn’t compatible with pre-WM5 operating systems and needs to be “hacked” in order to be able to run it on non-Phone Edition Pocket PC devices. (See the “Platform compatibility: non-phone PPC” row in the main chart to see how this hacking must be done.)
Note that the latest, currently available Jbed version has problems with the cookie handling of Opera Mini 4 beta 2. This means you can’t log in to many (but not all; for example, Yahoo Mail works) Web sites with OM4b2 running under Jbed. As this isn’t an issue with Opera Mini Mod 2.04/2.05, this seems to be a problem exclusively with the given Opera Mini version and not that of Jbed. If this is a problem, consider switching to another MIDlet manager (for example, Jeodek), where the cookies of Opera Mini 4 beta 2 do work.
2.2 Esmertec Jeodek
There are, basically, two versions of this KVM. The non-M3G-enabled, newer version isn’t really recommended (Jbed is definitely better in almost every respect, except for the Opera Mini 4 beta 2 cookie issues). There is, however, an older, M3G-enabled version out there, which allows for playing a wide variety of games. I’ve explained how the latter should be used HERE, in the 10/11/2007 update. That is, if you’re into gaming, you might want to go for the M3G version; otherwise, I recommend upgrading / switching to Jbed.
2.3 IBM J9
This is a well-known but, now that both Jblend and the two product lines of Esmertec are considerably better in most respects (except for some deliberate questions like the ability to run multiple MIDlets at the same time, in which it’s, together with TAO Intent, is clearly better than Esmertec’s products), not any more recommended KVM. You should prefer Jbed to it and only consider using it if you do need J9’s special capabilities or its compatibility with pre-WM5 operating systems.
Note that, lately, IBM has made much harder to download a trial version of J9 if you’re situated outside the States.
2.4 TAO Intent
This is the MIDlet manager having come with almost all HTC-manufactured WM5 Pocket PC’s and Smartphones. Now that the developer no longer exists, the HTC folks have switched to Esmertec Jeodek / Jbed instead (and independent MS Smartphone / PPC PE manufacturers like Sharp or Samsung prefer Aplix JBlend instead). However, this still means there’s a HUGE number of installed userbase of this MIDlet manager.
Currently, two major releases of these titles are widely used: the 10.1 series (also compatible with WM2003(SE) and the MS Smartphone platform) and the latest 11.1 series (the latter being only WM5+ & Pocket PC-compliant).
In general, you will want to prefer Jbed to this title. It has only few areas where it’s clearly better. Just like with IBM J9, in addition to WM2003(SE) support, it also supports running MIDlets concurrently.
If you have a (non-rebranded!) HTC WM6 Pocket PC device, go for the latest, .1036 version; otherwise (you have a rebranded and/or WM5 device), go for .1034. Should you have a plain (non-phone) Pocket PC, make sure you apply the SMS.dll / Phone.dll hacks already mentioned with Jbed.
Note that, at 4pda.ru, there is a separate “turbo” version. While I haven’t really measured remarkable speed increase with the jBenchmark tests, many users have reported generic speedup with at least starting / loading MIDlets. This is because many library files have been decompressed by the creator, meaning no decompression needed in runtime. This may indeed result in some speed increase. (Note that this trick doesn’t work the 10.1-series TAO Intent MIDlet managers (MM’s); this is why only the new series has a separate “turbo” version.) Note that this also means this version occupies about two times more storage than the non-turbo one; therefore, if you have little built-in storage, consider installing it on a storage card. Also, it’s a bit older (version 1023) than the – currently – latest, 1036 version.
2.5 Aplix JBlend
This OEM MIDlet manager comes with, compared to Esmertec’s KVM’s, very few Windows Mobile models. Compared to Jbed, it has both advantages and disadvantages; for example, it supports M3G (and, therefore, far more games) BUT it doesn’t support midi / MP3 playback (that is, you won’t really hear music anywhere) and has a messed-up security model making it pretty useless for Net access like Opera Mini or Gmail. This means you will only want to use it for gaming – if the other two, decent alternatives (the M3G-enabled Jeodek or Jbed) don’t work or work slower.
In THIS HowardForums thread, you’ll find many titles compatible with this MIDlet manager; and, of course, my main games compatibility chart will provide you with a lot of additional compatibility information with current MIDlets.
2.6. Not recommended KVM’s
Note that the charts (and this tutorial) don't elaborate on the following MIDlet managers:
2.6.1 NSICom CrE-ME
This manager is still (as of version 4.12) pretty weak (MIDP 1-only, really low resolution, problems with connecting to the Net, pretty complicated to install a MIDlet etc.). This means it, in most cases, should not be used. Strange the developers still call it "the world's most reliable J2ME/CDC Java Virtual Machine technology for Embedded platforms". While CrE-ME is without doubt the BEST JVM out there right now for running individual applications / applets (which are vastly different from MIDlets), its MIDlet support is really bad.
2.6.2 Coretek Delta Java Manager
This MIDlet manager is only slightly better than NSICom's above-mentioned CrE-ME. While it's compatible with quite a few games, it has severe problems; most importantly, its utilized screen estate is tied to 176*220 (fortunately, it’s pixel doubled on VGA devices). This means you won't be able to run your MIDlets using the real, full screen estate of your QVGA / VGA / WVGA Pocket PC's or QVGA Smartphones. Therefore, I only recommend it if you want to run MIDlets tied to 176*220 (or smaller) screen sizes and/or you have a 176*220 MS Smartphone.
A related (Russian) thread is HERE (BabelFish HERE)
2.6.3 Mitac JVM
This is an old (2003), pretty bad and not recommended MIDlet manager.

3. Introduction to using MIDlets
Now, let’s see how you can install (deploy) MIDlets on your Windows Mobile device and how you can use them. Fortunately, doing this is very simple.
First, make sure you do have a KVM on your handheld. If you don’t, install one. If you have a non-phone Pocket PC and want to use any MIDlet manager (except for IBM J9), make sure you install the SMS.dll and Phone.dll hacks and / or if you have a pre-WM5 device, you’ll need to choose from either IBM J9 or old versions of TAO Intent.
After this, your life will be pretty easy.
3.1 Two ways of deployment (installation): online vs. offline
In general, there are a lot of MIDlets available online. In general, if you click them on the Web from your Windows Mobile device (preferably, using a built-in Web browser), they get downloaded to your handheld and automatically deployed in your device. The same happens with JAR files you copy to your handheld and, then, deploy them locally by either making your KVM explicitly search for it or clicking it / pressing the Action button from a local file manager. In the following two subsections, I elaborate on these questions.
Note that, generally, there are two kinds of files you’ll run into: JAD files and JAR files. When you download a MIDlet to your desktop PC so that you can, later, deploy it into your handheld’s KVM, only download JAR files, not the JAD ones.
If there’s no way of directly accessing JAR files, only JAD ones (as is, for example, the case with the Opera Mini 4 beta download page HERE - note that you should visit it from a Wap-capable desktop browser (Opera), that is, NOT from IE!), the “Download high memory version” download link will download you a JAD file, not a JAR one. You can directly copy this file to your handheld but, then, it’ll need to have Internet connection to be able to download the JAR file referenced by the small JAD file. If you can’t guarantee this or prefer collecting the JAR files offline, do the following: open the JAD file you downloaded with a text / file viewer (editor) and look for the attribute named “MIDlet-Jar-URL”. Copy the URL after the colon (for example, http://mini.opera.com/dl/1B8GM15aEP5uj-jE8A4AACMhDw8C/mini.jar) to your desktop Web browser. Now, you’ll have direct access to the JAR file – you can already safely save it.
Note that some KVM’s support separating MIDlets into different folders. Some allow for selecting the folder at deployment time (an additional step in the deployment process; this is what, initially, the “root” screen stands for when deploying into Esmertec products), the others after deployment. (And, on the Nokia, as it has no MIDlet manager interface at all but all deployed MIDlets are listed as regular applications, you can use the system file explorer tools to move them elsewhere, in another folder. This is slightly different from the way MIDlets were handled or early MIDlet-capable Nokia phones like the N-Gage, where there was a separate folder for them.) Also see the “Possible to use folders for better MIDlet separation?” row in the main chart for more info & screenshots.
Also note that, during the deployment process, you will also need to let the installation continue, particularly when the given MIDlet isn’t signed with a trusted certificate. (The vast majority of MIDlets are like this.) This, in general, only means you will need to press the left softkey some times on both Windows Mobile and Symbian.
3.1.1 Offline: originating the deployment from inside the manager vs. doing the same from the outside
There are two ways of deploying a local MIDlet JAR file to your MIDlet browser. The easiest is the default way of just clicking / pressing the Action key while viewing it from a local file explorer tool. This, as long as the file associations are correctly set (which may NOT be the case if you install more than one KVM’s on your handheld – more on this later), will automatically invoke the JVM and deploy the MIDlet.
Another way to select the related menu item inside the given KVM is to search for JAR files in the local file system (for example, Menu / Install / Local with TAO and Menu / Install / Local Files with Esmertec’s KVM’s). Unfortunately, it’s pretty flawed with most of the KVM’s; for example, the lack of alphabetical sorting, some of them can’t display all the files at once if there are more than 200-250 of them, some are only looking in a given directory or have no search capabilities at all, which is the case with IBM J9. The latter, as it doesn’t allow for browsing the file system for a given JAR file, forces you to enter the full (local, that is, Error! Hyperlink reference not valid. ) URL of the JAR file, which is really a pain in the back. Finally, Jblend doesn’t offer any local file browsing / deployment at all – with it, you must initiate the deployment from any file explorer tool. The latter is “only” highly recommended with other KVM’s because of the other annoyances and bugs they have.
3.1.2 Online
This is much easier: you just navigate to the given page with the MIDlets online and just click the JAD (or JAR) files. Note that some KVM’s may not allow for installing Web-based JAR’s directly; with them, you will need to click the JAD file instead. This is in stark contrast with the local install: all the tested (non-disqualified) browsers allow for the direct installation of JAR files and no local JAD’s are needed.
3.2 Running the already-deployed MIDlets
After your MIDlet is deployed, you will need to click it from inside the KVM if it’s not started automatically: most current, recommended KVM’s ask the user whether the MIDlet should be started right after the deployment.
Otherwise, you just start the KVM environment (it’s, in general, in the main Start Menu / Programs folder (except for the HTC Kaiser / Tilt, where it’s in the Tools subdirectory there) and is called “Jbed”, “Java”, “Jeodek” or “Esmertec Jbed/Jeodek” with the Esmertec products, “MIDlet Manager” with TAO Intent, “Midlet HQ” with IBM J9 (linking emulator.exe) and “Jblend” with Jblend) and simply double-click the given, already-deployed MIDlet. With IBM J9, you must select the uppermost “Launch” menu item in Actions instead, after highlighting your MIDlet.
Now that I’ve made it clear it’s only Nokia’s (Symbian) MIDlet manager that puts the deployed MIDlet icons in the traditional Applications folder, you may also want to know whether you can also hack the Windows Mobile KVM’s to do the same. This, as you may have already guessed, also greatly speeds up starting a given MIDlet: you don’t need to start an additional layer of managers. The answer is: yes, with most KVM’s (except for Jblend), you can. Then, you won’t need to separately start the KVM interface to gain access to the deployed MIDlets. See the “Direct, system-level links (shortcuts) to MIDlets” row in the main chart for more info on this. Note that, as opposed to Nokia’s system-level links (or, for that matter, the way the excellent Palm OS emulator, StyleTap, works on Windows Mobile), all these links will have the same icon, unlike under Symbian – not that of the icon of the MIDlet itself. This is a definite disadvantage if you prefer looking for a MIDlet based on its icon and not its name / position.
3.3 Security issues
Unlike with native Windows Mobile (or Symbian) applications, you’ll always run into security prompts. Therefore, it’s worth knowing a bit about what they are all about.
Java programs, in general, put a lot of weight on security measurements. This is why they continuously prompt the user when they try to access “sensitive” resources like the Net or the local file system.
Fortunately, you can, in general (except for Jblend), easily get rid of this problem:
- if you have any of the Esmertec KVM’s, use the MIDlets signed by the MXit LifeStyle-signed JAR’s available in THIS thread. Note that I’ve separately linked in the most common non-game (games, in general, aren’t affected by these issues, unless they want to use Bluetooth) MIDlets you may want signed. Then, you’ll be able to set their security model for “Blanket”, which means you’ll never be prompted for permission. It’ll certainly be easier for you than with the default “Session” (you’re asked once per session – that is, after starting the MIDlet) and the even more restrictive “One Shot” security model. Incidentally, Jblend employs exclusively the latter model with accessing the Net; this means it’s pretty much useless for applications like Opera Mini or the Gmail MIDlet. This is particularly true with the Gmail client, where it prompts the user to allow going on upon downloading every single mail (header). That is, never use Gmail under Jblend.
- if you have a KVM where you can “hack” the security descriptor files (all Esmertec KVM’s and IBM J9 belong to here; TAO Intent is also said to be but the opinions do differ on the latter and I haven’t tested this hack), do the hacking to get rid of the annoying security prompts. See the “Security: Allow permanent Net access without prompting ("Blanket" security model, as opposed to "Session" / "Oneshot")?” row in the main chart for more info / links.

3.4 Runtime issues: concurrent (parallel) and background execution
The KVM’s slightly differ in how they handle concurrent execution of MIDlets – or, simply running something in the background. Some (TAO and J9) allow for the concurrent execution of MIDlets, while the rest don’t. This means the, otherwise, excellent Esmertec KVM’s will only run one MIDlet at a time, while the certainly, in most respects, inferior J9 and TAO Intent will run any number of them. TAO, in addition, also supports the in-environment switch between running MIDlets, unlike J9.
Support for parallel MIDlet execution can be very useful; for example, the Gmail MIDlet could continuously check Gmail for incoming messages, while, in another MIDlet, you could browse the Web. You can find some other uses for example HERE, in the comment section (the comments HERE are also pretty instructive and shed light on related issues).
The ability to execute a MIDlet in the background is also very important. Just an example: you start downloading a Web page in Opera Mini but quickly realize the download will take ages. In order to save time and do something useful in the meantime, you decide to minimize the Opera Mini task, do something else in another program and only return later, expecting Opera Mini has already finished downloading and rendering. All the tested WM and Symbian KVM’s support this kind of operation; the only exception is Jblend, which immediately pauses when it loses the focus. Incidentally, Jblend’s behavior also has some other consequences; for example, in no way can you use external character injectors to it (unless they’re continuously running and, therefore, don’t result in executing a new process; PQzII is one of these) and you will even have problems uploading Jbenchmark results to the server (because it constantly thinks the MIDlet has been paused and prompts you for resuming).
I also recommend Solnyshok’s excellent article for more information on the advantages of parallel execution of some MIDlets. Also note that the article contains an excellent hacking tutorial on how multiple instances of the same MIDlet can be executed at the same time.
4. The main chart
Again, this is where you’ll find most information. It contains an order of magnitude more information than the article you’re just reading in a well-condensed, tabular, easy-to-compare form, packed with tons of screenshots helping in finding out how a given feature should be enabled / used.
I’ve already elaborated on several (for example, security-related) of the rows this chart has; now, let me elaborate on the rest.
In the “Price / availability” row, as has already been stated, you’ll find where to get / download the given KVM from.
In the “Platform compatibility” group, I’ve listed three rows: compatibility with non-phone Pocket PC’s, Pocket PC Phone Edition devices and, finally, touchscreen-less Smartphones (abbreviated as SP’s).
As has already been pointed out, you MUST apply the SMS/Phone DLL hack explained in the Jeodek column if you have a phone-less, “classic” Pocket PC. Also, if you have a MS Smartphone (as opposed to Pocket PC’s), pay special attention to the compatibility remarks here as, unfortunately, not all titles are Smartphone-compliant or, if they are, you may encounter some problems when trying to run them.
The “Generic compliance with standards” group is more for techies: people that would like to know everything about the standards support of the given KVM. As can clearly be seen, the Nokia N95 KVM blows all the other KVM’s out of the water (in this respect too); this is particularly true of, under Windows Mobile, never (except for some very old and long-discontinued IBM J9-specific add-on projects I’ve elaborated on HERE) implemented, for, for example, multiplayer gaming (give a try to the MIDlet version of 3D Constructo Combat in multiplayer mode on even slower / older Nokias like the 6680 – you’ll LOVE it! The same stands for for example the infamous Naval Battle: Mission Commander) Bluetooth support. The same stands for other goodies like support for camera: all WM KVM’s lack the support for it, as can clearly be seen in the “MMAPI Video-capture” cell of the “JVM Multimedia (JSR 135)” row. It could be VERY useful; see for example the posts HERE, seeking for support for barcode reader applications. Audio capture (which isn’t really supported by many apps either) is also pretty useful; see for example the TellMe MIDlet for a real-world usage example. Yeah, you can clearly see MIDlets are in no way for gaming only – there have a LOT of enterprise uses and are particularly useful when you have a lot of different platforms you need to quickly develop a business solution for!
In the “JVM Memory” row, I’ve listed the appropriate heap (free memory) size available for each KVM. The more, the better for running memory-hungry MIDlets – unless the given KVM uses dynamic (de)allocation of memory when the need arises. Then, it’ll be able to run even the most memory-hungry MIDlets (for example, a full JBenchmark category, in High Quality, packed into one JAR). Unfortunately, only Nokia’s KVM and Jbed support the latter. Also note that you can set the memory allocated for Jblend in the Registry.
Support for “JVM M3G”, that is, the Mobile 3D Graphics API is the dream of most Java MIDlet gamers. As can be seen, several KVM’s support it. (Speed, without hardware acceleration, is another question.)
The “JVM File Connection” group is also very important, particularly with applications like Opera Mini Mod, the unofficial (and, unfortunately, illegal; therefore, I cannot provide a link to it either) “hack” of Opera Mini, adding a lot of goodies like (pretty rude, but still working) page saving and IEM favorite import / export. These all require access to the file system, which, unlike with real Java, isn’t built-in or required by the basic standard. This is why so few WM KVM’s support it: IBM J9 with an additional hack (I’ve elaborated on the installation in the chart) and Jbed. Interestingly, some real-world tests were failed by Jbed, while IBM J9 passed all of them. The support for accessing the local file system is certainly a big plus with IBM J9 – one of the very few advantages of the environment, along with, for example, the ability to run several MIDlets at the same time.
The “Storage usage” group is very important because internal storage memory is doomed to fill up very quickly (especially with low-end WM devices only having 64M of Flash ROM – an example is the HTC s310/Oxygen WM5 Smartphone), particularly if you install sizable games (current games are 300-600 kbytes in size). In this group, I’ve explained the following:
Where can a given MIDlet manager KVM be installed to – that is, can it be installed to a storage card? All of them can (note that we’re, mostly, dealing with XDA-Dev-created installers and hacks in here!), except for Jbed, which MAY require some additional manual file copying (also explained in the chart).
Where the deployed MIDlets are kept: This is also highly important. Fortunately, it’s only IBM J9 that is doomed to store the deployed MIDlets in the internal storage (I’ve tried to hack it to a card very hard – see my related article – but in vain); other MIDlet managers, when installed to a storage card, don’t. Note that, should Jblend and TAO be an OEM-installed KVM on your handset, you can still easily “hack” them to store their MIDlets on a storage card with a simple Registry edit.

In the “Text input” group, first, I’ve listed the copy / cut / paste capabilities of the KVM’s. One of the biggest problems with TAO is the complete lack of copy / paste functionality in any of its textboxes. This is a real pain in the back. Note that some 4pda users have implemented an external, not very reliable way of pasting text to the TAO textboxes (via MortScript), it’s still far from perfect.
“Known text input-related bugs? Maximal editable pre-populated text area size?” elaborates on the text input-related bugs of the tested KVM’s. The most important of them (without any exception – not even Nokia’s implementation did fare well in this respect) is the text input areas’ limited size. This means the following: when you, for example, post an answer in a forum using the “QUOTE” button, you may end up not being able to enter anything and/or your answer getting completely deleted. In general, the threshold is between 1 and 8 kilobytes, depending on the actual KVM and the Web browser you use (Opera Mini fares far better in this respect than its modded version; I think because the latter uses 16-bit Unicode for input, which take up double the memory as the 8-bit input of Opera Mini.) Therefore, make sure you either quote VERY short answers and try to remain under the threshold or try not to quote anything.
In addition, TAO has a very bad, additional bug: if the quoted (and/or, original) text contains line breaks, you won’t be able to edit it at all.
I really recommend giving the test HTML page I’ve created for this test a thorough try to see what restrictions there are, whether your input is retained (after you exit the edit mode) etc so that you can be absolutely sure you don’t mess up anything when you do start filling in Web forms or post to forums with Opera Mini (Mod).
The “Display” category contains information on the usage of font smoothing technologies like ClearType (also see THIS request). As can clearly be seen, it’s only when using the smallest character size and only with some KVM’s that there is font smoothing (with OM4b2)
I’ve devoted two separate rows (and a lot of screenshots) to demonstrate the font sizes of Opera Mini 4 beta 2 in both VGA and QVGA because a great deal of misinformation is all around the Net on the different font sizes of each. For this test, I’ve also created a test page. As can be seen, the font sizes are roughly equal with all KVM’s, as opposed to what some people state. Also note that I’ve also published how you can increase the font size in TAO with a simple Registry edit (I’ve also attached the import file) – the ability to do this is clearly is a definite advantage of TAO.
As far as the “Keyboard, SIP, softkeys” group is concerned, please read THIS for a very thorough explanation.
I’ve already elaborated on most rows of the “MIDlet installation, separation, direct invocation, uninstall” group; therefore, I won’t go into this once more. It’s probably only “Registry import files to quickly reassociate JAR / JAD files” that still hasn’t been explained. Please see the “2.4 Co-existing on the same Windows Mobile devices” section in the Definitive Guide to Running 3D-enabled Java MIDlets on Windows Mobile to see why you might need these Registry import files if you plan to use more than one KVM’s on your Windows Mobile device and want to retain (or, quickly restore) the ability of a given KVM to deploy a MIDlet you click on in an external (Windows Mobile) Web browser or in the file system.
The “Security” group has already been explained above.
The “Misc (sound, compatibility with some popular apps, proxy, etc)” group contains some miscellaneous tests and rows like
support for full screen: as can clearly be seen, in this regard, Jbed is the best (it indeed offers full screen) and Jeodek is the second (it only displays the upper task bar but not the lower menu bar; Jeodek M3G being the only exception when run on the MS Smartphone platform). So does Jblend. TAO and IBM J9, unfortunately, both display the two bars at the top and bottom. Needless to say, Nokia’s KVM also makes use of the full screen estate.
Sound support: as has turned out during the tests, Jbed (along with Nokia’s KVM) is by far the best KVM when it comes to playing in-game music. Note that I’ve tested it being stereo by running Doom RPG, a very famous MIDlet (even PocketGamer.org’s infamous Sponge likes it). Strangely, while Jbed does support stereo, Nokia has failed the stereo test: it only plays music in mono. At last something that Nokia’s KVM gets beaten at
Proxy support is also very important and in high demand among Opera Mini users (as Opera Mini, by default, doesn’t support proxies, unlike Opera Mini Mod, where you can enter the proxy address right in the browser settings). In these tests, I’ve used my custom-written Web client MIDlet and Web server to easily find out which of the several possible ways Opera Mini (or, any other Web browser not supporting custom, local proxy settings) can be made use a proxy. As can clearly be seen, only Jbed and IBM J9 support this. (I haven’t tested Nokia’s KVM in this respect; I assume it works OK.)
the compliance test of three highly popular productivity (non-game) MIDlets: Gmail, Opera Mini and Opera Mini Mod.
5. jBenchmark Benchmark Results
I’ve also made some serious benchmarks with the well-known jBenchmark suite.
First, it’s worth pointing out that, while Esmertec Jbed does promise speedup by compiled code, in reality, it doesn’t mean THAT big a speed increase. That is, you won’t even see a twofold speed increase in everyday apps / games – if there will be any speed difference at all. In the charts, I’ve emphasized the tests where Jbed produced FAR better results than other MIDlet managers running on the same device. I’ve used plain bold to emphasize differences up to two; to emphasize even bigger differences (for example, the Chess test), I’ve additionally used Italic and <u>Underline</u>.
It’s also worth pointing out that while high-resolution (VGA) devices (in the test, the Dell Axim x51v and the HTC Universal) tend to run standard 2D graphics tests (at times a LOT) slower than standard-resolution (QVGA) models like the HTC Wizard or the HTC Vox / s710, with 3D (with the only currently available, 3D-capable MIDlet manager, the TAO Intent 11.x series), the differences aren’t that big.
As far as the 3D benchmarks are concerned, which show a clear, sometimes 20-fold speed difference in favor of the 3D hardware accelerated Nokia N95, don’t think Windows Mobile devices are THAT bad at playing the currently available 3D games. While M3G games indeed run pretty much flawlessly on the Nokia N93(i), N95 and E90 (the current Nokias with 3D hardware acceleration), the currently available, non-accelerated Windows Mobile KVM’s don’t produce MUCH worse results either – most 3D games still remain playable under WM too. In practice, the 20-fold difference in these synthetic tests reduce to two to three-fold difference with currently available, tested 3D MIDlets. Never ever believe anyone that states the opposite – he or she, then, hasn’t compared (unaccelerated) Windows Mobile and (accelerated) N95. I did and know the difference, which is certainly not even tenfold, no matter what the JBenchmark results suggest. Note that the reason the Nokia N95 scores so good in 3D is not because the built-in PowerVR 3D chip would be so much faster than, currently, the 2700G. It’s just because the former is supported by the built-in MIDlet manager and the latter isn’t supported by any Windows Mobile MIDlet managers.
Otherwise, speed-wise, there’s no clear winner. In general, all MIDlet managers have their strengths and weaknesses; there isn’t a single one with the best speed / efficiency (not even that of Nokia). Also note that, in general, the Nokia benchmarks don’t differ much from those of the WM KVM’s – of course, the M3G results are completely different. But, again, with real MIDlets, this difference is far less pronounced than one would think based on the synthetic JBenchmark 3D results.
Note that the columns are a bit different from the first chart; now, I’ve also listed the device I’ve run the given MIDlet manager on.

6. Game compatibility reports
I’ve also thoroughly tested some hundred (!) popular, well-known games; both 2D and 3D titles. (More on these games in THIS article – my previous and, now, slightly outdated article on 3D gaming.)
As has already been emphasized with the benchmarks, there’s no clear winner here either. As a rule of thumb, however, you should always try to run a given title under Jbed first. It’s the least compatible with existing games, but has three real advantages over both the M3G-compliant version of Jeodek and Jblend: if it does work then, generally, it’s the fastest; of the three, it has the best sound emulation and it supports full screen mode.
If you do encounter problems, give a try to alternative MIDlet managers: to IBM J9, TAO Intent, Jeodek M3G or Jblend (or, JblendFullScreen if you don’t need M3G and/or decent music but do need full screen because of, for example, the hard-coded screen size used by the MIDlet). Note that it’s pretty useless to try to run a title not running under Jbed under the non-M3G-capable Jeodek either. Doing the same under the M3G-capable Jeodek version, however, is a completely different issue.
As has already been emphasized, these MIDlet managers can co-exist on the same device and if you’re really into gaming as many MIDlets as possible, you will want to put at least three (Jbed, Jblend and Jeodek M3G) on your handset.
Note that there is an earlier version of this chart HERE. As the chart doesn’t contain for example the Nokia N95, the M3G-capable Jblend (only its full screen, old and pretty much incapable version) and lists far fewer titles than the main games compatibility chart, it’s in no way as important as the main compatibility chart listing the, for gaming, most recommended WM KVM’s (along with Nokia). However, it also contains some info on how different hardware (520 MHz XScale-based VGA HTC Universal vs. 195 MHz TI OMAP-based QVGA Wizard, for example) compare when it comes to running (graphics-intensive) games. As can be seen, the, otherwise, for gaming not really recommended Wizard behaves pretty OK even at the default 195 MHz CPU clock speed.

The latter means you don’t need to install the somewhat older version .1023 of the MIDlet manager on your phone-less PPC any more.
Running Motorola-specific Midlet games on the Pocket PC? YES!!
IBM releases new, 6.1.1 version of great Midlet runner J9; now, it’s fully compatible with Google Maps!
Great, Free Java/Midlet Environment IBM J9 New, 6.1 Version is Out – a Full Compliance & Bug Report & Never Before Published Tweaks that Help Using It Much Easier (in there, I’ve also reported on my effort of trying to relocate the IBM J9 deployed MIDlet repository from the main memory).
Java Midlets on the Pocket PC - the Complete Tutorial (outdated, but nice for some additional tips)

UPDATE (11/23/2007):
in the meantime, thanks to XDA-Devs user defcomg, a new, third-party, free Bluetooth (JSR-82) library, BlueCove has been found, which supports IBM J9.
In the second part of this article, I elaborate on how you can “hack” some Nokia classes into MIDlets so that they have a chance to run. I also explain how you can force the installation of MIDlets that, otherwise, are refused to be deployed because of missing library (for example, Bluetooth under Jbed) support.
1. BlueCove
Let’s start with the compatibility issues.
1.1 Real-world (!) compatibility
First, it’s only IBM J9-compliant (NO TAO, NO Jbed, NO Jblend). Even under J9, unfortunately, it’s (as of this writing) pretty much far away from REALLY working. While it correctly implements Bluetooth discovery, in general, it doesn’t go further and just crashes at actually connecting (not only discovering). I’ve tested this with both the Microsoft and the Widcomm Bluetooth stack, using version 6.1.1 (that is, the latest one) of IBM J9.
My compliance test results are as follows:
Super Bluetooth Hack 1.07 (note that the two (2nd/3rd) versions are exactly the same): doesn’t even start (IncompatibleClassChangeError with Vector)
Blooover discovering works; the actual connection doesn’t (IncompatibleClassChangeError with javax.microedition.io.Connection).
3D Constructo Combat: The same: it is able to discover other devices:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
but, upon actually connecting to them (or, when you start it in server mode), it immediately crashes and exits.
1.2 Downloading, installing
If you still want to give it a try (again, it’s pretty much useless as of now!):
Get bluecove-2.0.1.jar (version as of 11/23/2007) from HERE
if you have WinRAR on your desktop Windows machine, enter the WinRAR bluecove-2.0.1.jar command;
otherwise, rename bluecove-2.0.1.jar to bluecove-2.0.1.zip and click it so that its content is shown;
extract bluecove_ce.dll and intelbth_ce.dll from the root of the archive; transfer them to the \bin subdirectory of your IBM J9 installation.
Note that if you don’t want to hunt for / extract these files yourself, I’ve made them available HERE as a standard ZIP file. Just unZIP it and transfer the two DLL's.
copy bluecove.jar to the \lib\jclMidp20\ext directory of your IBM J9 installation. If “ext” doesn’t exist, create it.
you’ll need to use special link files to start your Bluetooth-enabled MIDlets. This also means you don’t need to deploy your MIDlets under J9 at all as direct links of this type don’t require the MIDlets to be deployed beforehand. A typical link file looks like this:
255#"\Storage Card\ibm\bin\j9.exe" -jcl:midp20 -Dmicroedition.connection.pkgs=com.intel.bluetooth -cp MIDletName.jar "-jxe:\Storage Card\ibm\lib\jclMidp20\jclMidp20.jxe" MIDletName.jad
(An example link file is HERE as a real file.)
In here, change MIDletName to the filename of the MIDlet and, of course, change \Storage Card\ibm to the actual path of your IBM J9 installation.
Note that you’ll also need the JAD files in this setup. Should you not have them, use the free JADMaker to create them from JAR files (see the link for more info). If you don’t provide any absolute directories in the link file to the JAR / JAD files, then, you’ll need to copy the JAR file to the \lib\jclMidp20\ext directory of your IBM J9 installation before invoking the MIDlet through the link file. This is the same directory where bluecove.jar should reside. Also, the JAD file must be in the same directory as the lnk file itself.
2. Some additional hacking
2.1 Nokia classes missing in the game
If you try to run 3D Constructo Combat under J9 (I’ll elaborate on other MIDlet managers later), you’ll notice at once it doesn’t run. The sole reason for this is the lack of some Nokia-specific libraries in the MIDlet manager. You can, however, easily “hack” these classes into the JAR file of the MIDlet itself.
To do this, first, download THIS archive and unZIP it. Second, get WinRAR and, after installing it, enter the WinRAR jarfilename command to open the JAR (the main MIDlet) file. Now, just drag-and-drop the com directory (with all its subdirectories, of course) to the opened JAR file – making sure you don’t drop it on a directory, but in the root.
That’s all; now, your MIDlet might start.
Note that this definitely works with 3D Constructo Combat and J9 but will NOT work with Jbed, not even with the permission hacking I’ll explain in the following section.
(also see THIS Russian-language post for more info if interested. It doesn't contain much additional info, though.)
2.2 Permission hacking
As has been explained in the MIDlet Bible, some (very few!) MIDlets can’t even be deployed under Jbed (and other, less recommended) MIDlet managers. The reason for this is the deployment-time permission checking.
An example of these MIDlets is 3D Constructo Combat, which is refused to be deployed because of the unavailability of a library (here, a Bluetooth one):
You can easily help this and make MIDlets at least deployable (being actually runnable is another question). To do this, enter the WinRAR MidletFileName.jar command and extract the META-INF\MANIFEST.MF file. In there, look for the MIDlet-Permissions: row. For example, with 3D Constructo Combat, it’ll be the following:
MIDlet-Permissions: javax.microedition.io.Connector.bluetooth.client,javax.microedition.io.Connector.bluetooth.server
Just delete it and overwrite the original META-INF\MANIFEST.MF file with the new version, all this in the JAR file. Again, the new file no longer contains the MIDlet-Permissions: row. Now, the MIDlet at least becomes deployable as can also be seen in THIS screenshot. (This, again, doesn’t mean Jbed will be able to run it as well. It won’t, not even with the above-explained Nokia class hack.)

UPDATE (11/24/2007): At last: an M3G-capable, much more gaming-friendly Jbed version is out!
As is stated in the Bible (as can also be seen in the main game compliance chart), the recommended, current version of Jbed has very limited game compatibility. If you do want to use it and do need to run for example M3G titles, so far, you needed to turn to alternative and, in many respects, inferior MIDlet managers. Now, this has changed: thanks to XDA-Devs forum members viperj and defcomg, a brand new and really great version has been posted.
This is version 070524.2.1 - that is, slightly older than the current, 070802.2.2 version. The major disadvantage of this version, compared to the 2.2 one, is the complete lack of sound emulation.
It runs all the games running under the old, M3G-capable Jeodek (see their list HERE) and is very fast. Furthermore, it isn’t affected by the locale bug of version 2.2 – that is, the inability to run under any locales using a language with a non-Western alphabet (for example, most East-European languages).
I’ve tested it with I-Play’s FIA World Rally Championship 3D, Namco’s Arcade Golf and High Speed 3D. All these worked flawlessly (except for, of course, the complete lack of sound), unlike under 2.2. Under 2.2, they didn't even start or crashed later.
If you really need sound emulation and it’s indeed able to run the given title, you will still want to version 2.2 of Jbed, though. For example, it runs Simcity Societies with great sound.
Installation
To install it, just grab THIS file, unRAR it to, preferably, the “J” subdirectory on your storage card (so that jbed.exe is right in the “J” subdirectory) and import THIS Registry import file (change all occurrences of "Storage Card" to the name of your card if it has another name). You might also want to copy a link to the main executable, jbed.exe, to \Windows\Start Menu\Programs (or, just \Windows\Start Menu\ on MS Smartphones). I’ve created the link file HERE.

UPDATE (01/16/2008): In the meantime, it has turned out that you can use the non-M3G-specific version of Jbed (that is, Cloudyfa's 20070802.2.1) with any localizaton setting if and only if you start your specific MIDlet directly; that is, via a system-level shortcut.
I've also been using Opera Mini 4 on the Blackberry 8800, using the default MIDlet manager coming with the device. Note that, unlike the built-in Web browser and the mailer, you MUST specify the APN of your operator for it to work. Otherwise, it'll just report being unable to connect to the Net after starting (and a lengthy installation process). To do this, go to Options / Advanced / TCP?IP and enter your APN (for example, "Internet" with T-Mobile.)

UPDATE (02/01/2008):
There are new builds of both Jbed and Jblend (two excellent MIDlet Managers – see the Java MIDlet Bible for more info). Due to lack of time, I haven’t tested them. Both has been done by Da_G (his projects’ homepage is HERE) and are accessible HERE. Note that you MUST register yourself (it’s free and is done quickly) in order to access the page above (along with the download).
I hope I’ll be able to test them some time – along with the default Blackberry MIDlet manager. (I might wait with testing the latter until version 4.5 of BB OS is released, though.)

UPDATE (02/06/2008): Another Jbed MIDlet Manager version has been released: JRebeiro_EsmertecJbed_20071119.3.1.
It’s available HERE (at the bottom of the first page).
As I don’t have the time to thoroughly test it, feedback is REALLY welcome!

UPDATE (03/09/2008): Sun to develop MIDlet manager for Apple's iPhone?
NOTE: this isn't strictly a Windows Mobile news item (albeit it also contains Windows Mobile references; see for example the Sun MIDlet Manager on some new HP’s). However, now that I've spoken to the Sun reps at MWC (I'm a Java guru and have also worked for Sun as a lecturer for their Java programming courses) and also spotted their own MIDlet manager on the HP iPAQ 610 series, I found it necessary to report on this.
Finnish mag Tietokone has just reported on Sun's wanting to develop a JVM for iPhone so that it can run the vast number of MIDlets out there (including, for example, Opera Mini and thousands of games, some of them - like Simcity Societies - of very high quality).
Interestingly, Steve Jobs (of Apple), who still haven't commented on Sun's announcement, earlier stated in NYT "noone uses Java any more". Sour grapes? (It was, so far, impossible to run third-party apps on iPhone - except for some, just-released titles like CorePlayer.) I pretty much think he quickly changes his opinion - after all, a decent MIDlet Manager would be more than welcome on iPhone, which still lacks third-party apps / games.
It's nice to see Sun indeed plans to port their stuff to iPhone. While their Windows Mobile implementation, according to some Opera Mini users, has a lot to be desired (I haven't personally checked the validity of their claims so I may be entirely wrong), I really hope Sun starts to take mobile platforms more seriously.

UPDATE (03/13/2008): New MIDlet manager in development: PhoneME; Jbed for WM2003(SE) released!
There are two pieces of news for everyone interested in running Java MIDlets. The first will be having a pre-WM5 device and wanting to run Java MIDlets (for example, Opera Mini) on it. Yes, at last, some Russian hackers made Jbed, the industry-leading MIDlet manager work under WM2003(SE)! The second (and, for most people, not that important) piece of news concerns a brand new MIDlet manager port for Windows Mobile.
1. Some Russian hackers, including the 4pda.ru folks, have, at last, managed to make Jbed, the best MIDlet manager, work under WM2003 and WM2003SE. The importance of this just can’t be stressed enough: so far, you only had the really inferior IBM J9 and the 10-series TAO MIDlet Manager to run MIDlets on pre-WM5 operating systems. Now, this has dramatically changed. Now, nothing will stop you from using Opera Mini on your pre-WM5 Pocket PC.
The direct link to these WM2003(SE) MIDlet Managers are as follows. There are three versions: a modded one, a non-3D one and a 3D one; all with a heap size fix.
JBed3dMod_HeapSizeFix
Esmertec Jbed heapfix
Esmertec Jbed3d heapfix
They have also made a MAJOR update to their 4PDA.ru MIDlet article, linking to all the contemporary Esmertec, TAO etc. versions (including ones with heap fixes, with and without 3D support etc.); the above links can also be found in their article. You can see the translation of the new page HERE (Google) and HERE (Babelfish). Note that I’ve kept the original page HERE (Google) and HERE for historical reasons for people interested in the pre-Esmertec times.
2. Now, the other piece of news, which, again, won’t be of that much interest to non-WM2003 / non-Java hackers.
Java is a really viable programming platform. Not only several high-quality games make it worthwhile, but also probably the best and, if you’re lucky enough with your geographical location, fastest and most bandwidth usage-friendly mobile browser available for mobile phones (including Windows Mobile), Opera Mini 4.
I’ve already devoted an entire all-in-one Bible to running Java on Windows Mobile (and Symbian). Now, let me introduce the latest Windows Mobile KVM: PhoneME.
PhoneME is another "let’s bring Java to various platforms” projects (official homepage HERE), which has recently received Windows Mobile support.
The main homepage of the Windows Mobile port is HERE (do NOT get the ones at the official download page of the project - they’re outdated!) Should you want to download the MIDlet manager, get the file starting with "phoneME Feature – MIDP” from the download page.
Get the CAB file; install it. (I assume you install it in the main storage of your handset; my MIDlet manager main lnk file and registry import file will be tailored for this install location.) After this, you’ll need to associate JAR files with the app; to do this, you’ll need THIS file (import it into the Registry!). You might also want to invoke the MIDlet manager directly; for this, you’ll need THIS file.
Unfortunately, currently, the MIDlet manager is pretty much useless; for example, it seems to be impossible to deploy Opera Mini 4 under the current (8525) MIDlet manager version:
(Interestingly, the 4PDA.ru folks reported they managed to deploy an older version of OM; however, they didn’t particularly like the way it ran. That is, they also state the current version has a lot to be desired.)
All in all, you will NOT want to check it out in its present form. I’ll try to let you know when a considerably better, more advanced version is released.
Still speaking of the project, the Personal version (not to be mistaken for the MIDP MIDlet manager!) seems to run standalone (Personal profile) apps OK (it does NOT have an Internet Explorer Mobile applet plug-in, though). An example of running the Hello World application available on the homepage as a separate download:
(Should you want to give it a try, assuming you installed the MIDlet manager in the built-in storage of your handset, use an invocation .lnk file with the following contents:
254#"\phoneme\personal\bin\cvm.exe" -cp "\phoneme\hello" Hello
Also make sure you unZIP the contents of the archive to \phoneme\hello.)
That is, if you’re into running Personal Profile applications (and not MIDlets), you might want to give it a more thorough try.
(Thanks to my blog reader thevery for drawing my attention to the project!)

4PDA.ru’s related discussion (translated) HERE (Google) and HERE (Babelfish).

UPDATE (03/14/2008):
a. unfortunately, the WM2003(SE) Jbed version has turned out to be only compatible with Pocket PC Phone Edition devices, NOT plain (phone-less) Pocket PC’s. There still aren’t WM2003(SE)-compliant SMS.dll and phone.dll files. These two files are needed on WM5+ standard (“classic”) Pocket PC’s to make Esmertec’s products / Jblend work. While the “hacked” DLL’s are compatible with WM5+, they aren’t with previous operating systems. That is, you’ll need to wait for a WM2003(SE)-compliant set of “hacked” DLL’s to be released.
Also note that there are some WM2003SE Phone Edition models that seem to be completely incompatible with; most importantly, the Qtek 2020i.
Also note that some? all? of the (again, currently, only WM2003(SE) Phone Edition-compliant – do NOT bother if you only have a phone-less PDA!) contain wired-in paths. For example, the one linked to from THIS page (see daemonpnz’s post at 10.02.08 10:22:56) must be extracted to “\Storage Card\jbed0524\”. Should you want to put it somewhere else (because, for example, your PPC PE device is a non-English one), you’ll need to hexedit Jbed.exe inside the RAR file and change the two occurrences of the above path to your liking. An example showing changing the space character to a B in "Storage Card".
(Incidentally, the reason for this was the following: I’ve tested it on my HP iPAQ 2210, which is a dual-slot machine, using the card names SD Card and CF Card. As you aren’t allowed to create a directory named “Storage Card” in the root of the file system, I had to hexedit the file so that it uses another name. “StorageBCard” can already be created. Note that, as the HP iPAQ 2210 is a no-phone device, this didn’t help much as it still refuses to run. Again, because of the still-missing, WM2003(SE)-compliant SMS.dll and phone.dll files.)
I let you know when Jbed becomes compatible with non-phone pre-WM5 devices.
b. I’ve also tested some of the versions linked from the 4PDA.ru thread on my HTC Vox (s710) to find out whether they’re any good compared to the old MIDlet managers; particularly Cloudyfa’s version - the version that, so far, I’ve recommended to all MIDlet users (unless in need for M3G (3D) support.). These two are both “fixed heap” versions; some of the less simple games (for example, DoomRPG) and benchmark apps with large memory requirements are stated to run much better / more reliably in the fixed heap versions than in the regular ones (for example, that of Cloudyfa) because of the much bigger available memory. I haven’t tested the effects of this myself.
1. JBed3dMod_HeapSizeFix (that is, 3D-capable Jbed version, based on 20070524.2.1, with fixed heap)
I was really interested in how this (and an additional, hacked file available for download HERE - just overwrite JBed.exe of the original, already-installed version with JBed3d_SreenFix.exe after renaming) worked because, at 4PDA.ru, there’s a version that promises flawless, screen problem-free functionality on MS Smartphones also compatible with the excellent Gmail client MIDlet.
(Also see THIS (original HERE) for more info; see freesunny's post at 10.01.08 10:56:06.)
So far, it seemed impossible to make the latter (the Gmail MIDlet) flawlessly work on MS Smartphones under any version of Jbed. An example of the display problems the non-hacked version (or any Jbed version) can be seen in the following screenshot:
Unfortunately, the hacked version (after overwriting the EXE file with the separately downloaded JBed3d_SreenFix.exe) doesn’t really work with Gmail: while indeed the entire screen estate is used, the three lowermost menu items (Search, Compose New, Exit) aren’t visible, just like with the non-hacked case:
Note that essentially the same results from the 4pda.ru folks can be HERE. The same problem also exists in Portrait mode, not only in Landscape.
All in all, while it’s certainly a step in the right direction, you will still have problems with (at least) the Gmail MIDlet. If you absolutely hate the missing display area in the MIDlet listing on MS Smartphones with the old Jbed versions, you might want to consider upgrading, though.
2. I’ve tested JBedModHeapFix (02.01.08) too – a somewhat extended and fixed Jbed version. While it does have certain advantages over Clodyfa’s version, it entirely lacks music support and is based on the 20070802.2.1 version – that is, the same “old” version as that of Clodyfa and not anything newer. I don’t really recommend it if you need sounds / music, which is excellent in the Cloudyfa version – again, unlike any other (earlier!) versions I’ve tested, including earlier Jeodek versions like the 20070425.1.1 version coming in the original (and just-updated) firmware of the HTC Vox / s710 and having very bad and distorted sound.
Note that the Jbed version lacks the the English jbed.exe.0409.mui file – it only has the Russian localization, that is, jbed.exe.0419.mui. This means, unless you copy the (standard) jbed.exe.0409.mui file from, say, the Cloudyfa version to the new one, it’ll have messed-up, invisible menus.
I’ve also tested whether these two versions, finally, fix the two biggest problems with the Cloudyfa version:
it’s not possible to install Cloudyfa’s version on the storage card: with the new Jbed version, it’s possible – without any manual hacking. In this regard, it’s much more recommended than Cloudyfa’s. (Haven’t tested the Jbed3D version in this regard.). That is, you can safely direct the CAB installers to install the managers onto a card: they WILL be installed there, not taking up any built-in storage.
with Cloudyfa’s version, it’s not possible to start MIDlets from inside the Jbed interface if you use a localization using not strictly Western characters:
Fortunately, both the non-3D and the 3D versions available at 4PDA.ru are compatible with non-Western regional settings, unlike Cloudyfa’s version.
(Note that, in the original Cloudyfa version, you can still execute MIDlets via a direct invocation link file if you have an otherwise incompatible regional setting, circumventing the standard interface listing all your MIDlets. This, however, needs some additional tinkering and, again, you won’t be able to select the MIDlet you’d like to run from the built-in list of the MIDlet manager. Also note that I’m speaking of the generic Regional settings, NOT the language of MS Smartphones (you can easily change the entire interface language of MS Smartphone devices.). Your MS Smartphone language may be, say, East-European; if you still use some non-Eastern regional setting, the apps started from inside Cloudyfa’s version will still run and you won’t need to use direct invocation link files.)
Also note that neither of these versions have any sound emulation. This, again, isn’t a change from the previous 3D (M3G)-compliant version but can be VERY bad news for plain non-M3G-compliant Jbed users, as, again, the Cloudyfa version has excellent music / sound emulation. That is, stick to the latter if you need music.

UPDATE (some 5 hours later): I’ve also tested the latest Jbed version, JRebeiro_EsmertecJbed_20071119.3.1. I’ve already mentioned it HERE but, then, I didn’t have the time to thoroughly test it.
The bad
- not possible to install it to a storage card by default
- display problems on MS Smartphones (as with all the other Esmertec Jbed versions – except for the M3G-specific, hacked 4pda.ru version). Note that, again, this doesn’t have any effect on how Opera Mini 4 or games work; only the main MIDlet manager MIDlet lists and, for example, the Gmail MIDlet are affected
The good
- the latest version; reported to be very fast
- M3G compliant
- has sound (as with Cloudyfa’s version)!!
All in all, highly recommended for gamers.
It’s available HERE (mirrored HERE so that you don’t need to search / register).
Also see THIS German language Pocket Players Reloaded article on the games it’s compatible with.

UPDATE (04/05/2008):
In the meantime, I’ve tested two versions of the latest, 3.1 version of Jbed and found out the following (starting with, currently, the latest and, unless you MUST install it on your storage card without any manual hacking, most recommended version):
1. Jbed Java 3.1 20080222 (available HERE; mirrored HERE for your convenience): this version runs flawlessly under WM5 (not only WM6 – note that some older versions of 3.1 are NOT WM5-compliant). It supports 3D (tested with Need for speed carbon and Night Fever; neither of them run under the non-3D-capable Cloudyfa 2.1), (as usual, excellent) sound. It can’t be directly installed onto a storage card, however. (As with some older versions, it’s possible it can be hacked there, though, with some manual file copying and registry / start menu link rewriting – I haven’t tested this.)
2. I’ve also thoroughly tested JBed_20071119.3.1_3dMod_HeapSizeFix_v2_wm6(lovetz1) linked from THIS MoDaCo thread. As a plus, it can be directly installed on a storage card, as opposed to the version above. It, however, doesn’t support sound at all. Otherwise, it seems it’s pretty much the same as the version above – except for WM5-compliance: I haven’t tested the WM5-compliant subversion. Again, I’d stick with the 20080222 (the first) version unless you really need every single byte in your built-in storage.
3. Note that neither version was able to run the s60v3 (Nokia) version of Command & Conquer 3: Tiberium Wars, the latest-and-greatest real-time strategy from EA Mobile – upon loading the mission (and displaying the progress bar), it just locks up. (Needless to say, it’s working flawlessly on the Nokia N95 v20). It seems no Jbed version is compatible with this excellent game – I’ve tested with several. This means the extended, “hacked” heap didn’t help with particular game. It might help with others, though.
4. Also note that the first beta of Opera Mini 4.1 has been released in the meantime. It simply ROCKS and is a must. See THIS for a complete review & tutorial.

hey Menneisyys.
i am running Command & Conquer 3: Tiberium Wars ,perfectly on asus p525 with JBED build 20070524.2.1 .
by the way i found a bug on asus p525 in all jbed versions over 20070524.2.1 and its just you can play games with joystick not the keypad (keypad if i press 6 to go right ,it will go right and stick to the right like its stuck,i cant move anymore till i exit the game) .
i have tested all 3d java emulator you mentioned on the bible and some that you didnt .
i have 4 java vjm installed together on my device , 3 jbeds :
1. is the latest build Jbed Java 3.1 20080222
2.JBed_20071119.3.1_3dMod_HeapSizeFix_v2_wm6(lovetz1 )
3.JBED build 20070524.2.1
4.jblend 20070413 a
every java game i try on 4 of them .

UPDATE (04/11/2008): XDA-Devs forum member Ebenezer has released a version of Jbed 20080222 3.1 that can be directly installed to a storage card. It also supports sound and M3G (3D). Make sure you switch to this version if you prefer keeping your MIDlet manager and deployed MIDlets on your storage card. I've also got rid of the old, 2.1 Cloudyfa version (along with all the previously-mirrored and, now, outdated Jbed versions - this is why the old mirror links will no longer live) and made the new version of Jbed available HERE for direct download.

Windows Mobile News as of 11/02/2007

As you may have noticed, I’ve started working on the Multimedia Bible, the premier resource of all info on multimedia playback, streaming etc. I don’t know when I get it ready. I’ll announce when the first chart versions are ready for public scrutiny.
After some 13-14 months of the 2.x -> 3.x series jump, the excellent S-K folks have just announced they will release a brand new, 4.0 version of SKTools, the, IMHO, best (albeit a bit overwhelming and, because of its capabilities and complexity, hard-to-discover) all-in-one systems management tool available for Windows Mobile. The new version will have the following new features:
- Cab Manager: SKTools can show all CAB,CPF,TSK files on device, show content (with full names, installation path, registry keys, shortcuts, _setup.xml), extract with full names, install to ANY location (full installation made by SKTools) for WM5/ WM6; SKTools can be associated with CAB files
- Replaced ROM Files: show which ROM files have been replaced by another version, show version and date of these files; the user can see if the "newest" file (the file having the latest time stamp) is, in reality, older than others and, therefore, remove it.
- Move Data: move application, folders, files to any location with automatic (!) registry and shortcut modification (and other data about files and their path)
- Storage Analyzer: show what files and folders (by types, attributes, ...) are stored on the device
The open beta starts next week (I already have a pre-beta); I’ll let you know when it becomes ready.
I’ve reported on LogMeIn Rescue Mobile more than two months ago. Now, a similar product, LogMeIn Hamachi has also been released, which – as opposed to ALL the other, similar tools – even the otherwise BEST Pocket Controller by SOTI – uses HTTP(S) tunneling for remotely controlling your Windows Mobile handheld from a remote desktop PC. This means any Windows Mobile device can be accessed, even ones behind firewalls and/or in NAT’ed networks (like about 60-70% of current mobile networks). See THIS and THIS MoDaCo threads for more info.
Spb has just released an updated version of their flagship, brand new product, Spb Pocket Plus 4.0, of which I’ve reviewed some modules HERE and HERE.
The dialup-sharing-over-Wi-Fi (which is of extreme importance with non-BT DUN and/or non-BT PAN-capable devices like, for example, Symbian smartphones (neither of them) or other Windows Mobile PDA’s based on the MS BT stack (no PAN support)) method (see THIS) has been GREATLY enhanced and automatized. See XDA-Dev forum member TalynOne’s excellent tutorial and tools HERE.
Moving to dialup and DUN: XDA-Dev forum member Technology has come up with a decent tool for making it work on the T-Mobile Dash.
CrazySoft released another puzzle adventure game
Their last “adventure”, “Lost in the Pyramid”, was a complete disaster. The new game is certainly MUCH better, albeit I’ve found some of the steps similarly illogical and/or plain stupid (for example, dying right away if you smash a tile; getting caught by the guards if you, for example, exit your prison through the window etc.). It’s still a far cry away from “real” (even emulated – see my emulation-related roundups and Bibles HERE) adventures like those of Legend Entertainment or Fade Team (Fade / Acedior), but you may want to give it a try nonetheless. Be warned: the trial can be played through in 10-15 minutes and I’m not really sure whether the full game is really worth the money. I’ll wait for either Eric’s or Ben’s reviews; I definitely won’t request a review copy (because I don’t really like biting the feeding hand, which, I think, may happen this time too.)
Therefore, just some remarks: The game is multiplatform and supports both VGA and QVGA on the Pocket PC. I’ve tested it on both VGA and QVGA Pocket PC’s, QVGA Smartphones and the Symbian S60v3 Nokia N95. With the latter two platforms, it’s pretty hard to control because of the lack of the touchscreen (and a sophisticated control system). At least you can use the 3…0 buttons to quickly access the inventory items.

Opera Mini 4: A new star is born - the FREE(!) Web browser you MUST give a try to

Opera Mini has a short history (the project was started only slightly over two years ago), but, today, with the release of version 4, it has become one of the most useful, best browsers available for anything handheld.
In this review & tutorial, I provide you with a complete tutorial of installing and using this recently released browser and, in addition, I explain why you may want to prefer it to other Web browsers.
First, some screenshots taken on wildly different platforms / devices:

Note that note of the above screenshots use real full screen mode – hence the top and bottom bars. The last screenshot with enabled full screen mode can be seen in the following screenshot:
1.1 Why you will want to use it?
You’ll find it a god-send particularly when
you’re over a VERY slow (for example, GPRS) connection and want the fastest browsing solution, preferably with images
yours isn’t an unlimited data plan; that is, you pay big bucks for every Megabytes
you don’t want to pay for a third-party browser (they, in general, cost big bucks)
you’re a desktop Opera user (you should be – give it a try, you’ll love it, particularly if you have a notebook with a high-resolution (at least SXGA+) screen – Opera’s zoom-in features are way better than those of Internet Explorer and are only matched by Mozilla) and you want to synchronize your bookmarks with it as easily and automatically as possible
you look for an easy-to-use, non-separate, integrated RSS reader – that is, you need a Web browser that also notifies you when you surf to a page also having RSS feed
your mobile device is resource-constrained, while you’d like to keep tens of Web pages, preferably with images, open at the same time (without the need for reloading). This is where most (if not ALL) other browsers severely fail, even on high-end mobile devices packed with tens of Megabytes of free (!) RAM memory.
you want something like the minimap feature of the Nokia Web browser on newer Nokia devices, the NetFront 3.4 Technical Previews (which, being just previews, are severely restricted and lack Flash, more than 10 favorites and other goodies) on Windows Mobile or the iPhone Safari browser but usable on any platform (incl. any Windows Mobile device) – but even faster and having much less resource demands
you want something with hardware button / keypad support. Opera Mini supports them just great. If yours is a phone with the dialpad on the front of your phone, you’ll REALLY love these shortcuts because, then, you will rarely (if ever) need to use the softkeys (or, on touchscreen devices, the stylus) to navigate the menus. Using button shortcuts is WAY faster. As opposed to this, (on Windows Mobile) NetFront and Minimo doesn’t support buttons at all and (on Symbian) Nokia Web isn’t very good either. The MS Smartphone version of IEM is, shortcut button support-wise, is also definitely inferior to Opera Mini – it supports far fewer operations than Opera Mini.
In the following two sections, I compare it to the other browsers available for the two current, major mobile operating systems, Windows Mobile and Symbian. (Freely skip the one not pertaining to you.)
1.1.1 How does it compare to other Windows Mobile browsers?
While there’re quite a few Web browsers on Windows Mobile, only few of them are actually usable: the built-in Internet Explorer Mobile (preferably with a capable plug-in like PIEPlus, Spb Pocket Plus 4.x (but NOT older versions) or MultiIE), Opera Mobile and NetFront. These three browsers (and the other Web browsers and IEM plug-ins I, generally, don’t really recommend: Picsel, Thunderhawk, Minimo etc.) all have their strengths and weaknesses, on which I’ve thoroughly elaborated in my two (a separate one for Windows Mobile Pocket PC’s and Smartphones HERE and HERE, respectively) Web Browsing Bibles
1.1.2 How does it compare to other Symbian browsers?
On Symbian, there’re two other, really decent Web browsers.
Opera Mobile is available for all S60 v2 (!) and v3 devices and is pretty decent. For example, unlike its Windows Mobile counterpart, it supports in-page text searching (which is painfully missing from the WM version). It, however, doesn’t use a compression service, which means long downloading times over slow links and has pretty high memory requirements.
Nokia’s Web browser coming with all S60v3 FP1 models is also very decent: it supports in-page searching, Flash Lite, minimap view and a lot of other goodies. However, it’s decidedly slower than Opera Mini and if your phone is a Nokia N95-1 with 64M RAM only, you’ll inevitably run into the MAJOR problems caused by its taking a lot of memory.
While Opera Mini 4 allocates about 10 Mbytes of memory to itself (which is a big letdown on the N95-1), after the initial memory allocation, no more memory will be allocated and you can safely go on browsing.
1.1.3 When will you still need to stick to a traditional Web browser?
Unfortunately, there’re several areas Opera Mini doesn’t excel at. While, say, 95% of the time it works just wonderfully (no wonder I use it for most of my Web browsing on both Windows Mobile and Symbian phones) for just accessing the Web, in the remaining 5% you’ll need to “fall back” to other, traditional, non-Java-based browsers. You wi
if you need full JavaScript and/or AJAX support. Only a subset of these standards are supported (albeit still a LOT more than in Internet Explorer Mobile, Thunderhawk or Picsel!). See THIS for more info if interested.
These browsers will inevitably be invoked when you make Opera Mini download a file (this, however, doesn’t mean you will need to stick to using these browsers!)
As you can’t make Opera Mini the default system browser, links received in e-mails and HTML files in the local file system will still need to be browsed via these browsers – unless (if it’s a remote Web page, not a local, say, HTML file or file attachment) you paste the address of the page to the address bar of Opera Mini (OM for short).
If you need Java applet and/or Flash (Lite) support. It’s with very few pages that you do need them; for example, Handango’s Friday giveouts, requiring full Flash compliance, are one of them. And, for YouTube, you will want to use alternate methods to play, NOT direct, in-line playback. (If you do use the TCPMP plug-in under Windows Mobile, then, you will still need to use IEM.) That is, generally, it’s when you want to play some online Flash games (see THIS Flash Bible for more info if interested) that you will need to stick to a browser supporting Flash.
There are some other restrictions; for example, you absolutely MUST edit text longer than 4-5 kilobytes. Then, because of the MIDlet Manager (also abbreviated as KVM) restrictions, you’ll end up having to switch to a “real” browser – at least for the time of editing.
You need to save Web pages to the local file system and/or copy text out of them. Unfortunately, OM is completely unable to do this. Unfortunately, with current KVM’s, not even copying a URL (for example, that of the current page) to the clipboard is possible.
Again and again, speaking out of experience, a casual user will very rarely need to switch back to these browsers and, after finding out how easy Opera Mini is to use, how quick it is to load pages and operate and how wonderfully low system requirements it has, he or she will want to stick with Opera Mobile.

1.2 Installation
(Note that this section only contains WM5+ Windows Mobile Pocket PC screenshots showing the MIDlet manager Jbed. As I recommend Jbed the most and I do urge you to install Jbed on your phone too, I didn’t bother including screenshots / instructions on installing OM under other MIDlet managers. Similarly, I don’t give you Symbian screenshots either – installing and running OM is done in a very similar way as under WM.)
1.2.1 Installing a MIDlet Manager
If you have a Windows Mobile device with at least WM5 as the operating system (sorry, previous operating systems aren’t supported – not even WM2003SE, let alone even older OS’es) and it’s not the latest models (for example, the Kaiser / Mda Vario III / Tilt) of HTC, then, you will want to download the Jbed MIDlet Manager HERE. If you do this on your desktop computer, transfer the CAB file to your handset and click / activate it from File Explorer (or any other explorer tool like Total Commander). Just install it (it’ll be installed in the main memory) and you’re set – you can go on installing Opera Mini itself.
Jbed will run on ALL Pocket PC’s and Smartphones running at least WM5. If you have an earlier operating system, check out the “Platform compatibility” section (with three rows corresponding to non-phone-enabled Pocket PC’s, Pocket PC Phone Edition and MS Smartphones in turn) in the main MIDlet Bible chart for download links; then, you’ll want to use either TAO Intent or IBM J9. Of the two, I’d prefer the former, but that’s only me.
Note that you can ONLY use this MIDlet manager if and only if your locale is set to a language using Western characters: Spain, France, Finland, you got it. (This doesn’t only cover Western languages; for example, Estonian only uses letters already present in some other Western languages. That is, while Estonian is an East-European language / locale, it’ll still work.) If, on the other hand, you have a, say, Slavonic locale (for example, Slovak), Jbed will NOT work. If your locale is Russian, then, you will want to check out THIS file instead; linked from HERE. Note that the latter MIGHT work with other East-European locales; I haven’t tested this myself.
Also note that if you have a non-phone WM5+ Pocket PC (for example, a Dell Axim x50(v) (with the WM5 upgrade) /x51(v) etc.), you will also need to download THIS file and unZIP its contents to \Windows on your Pocket PC.
1.2.2 Installing Opera Mini itself
If you’d like to download the browser onto your desktop computer and, then, transfer it to your phone, go to THIS page and click the opera-mini-advanced.jar link (I don’t provide a direct link to the latter as it always changes, as newer and newer builds are released). A JAR file will be downloaded. Transfer it to your PDA via ActiveSync, a memory card, a wireless connection, the WinCE File System plug-in of Total Commander etc., fire up Pocket File Explorer on your phone and click it. It’ll initiate the install process.
If, on the other hand, you’d like to do this on your phone, enter the address http://mini.opera.com/ into any of your Web browser on your phone (screenshot HERE) , scroll down and click “Try the new Opera Mini 4” link. This will take you to the page http://mini.opera.com/?rel=4, where you only need to click “Download high memory version”. Then, the installation will start – just like with the offline process outlined in above.
It’s pretty easy to install Opera Mini. You’ll just need to answer OK, Yes and Continue. For example, when you’re presented THIS screen (asking you whether OM should be put in the root folder or any subfolder), THIS and THIS question to to launch it. During the process, you’ll see other dialogs; for example, THIS showing the compilation process.
Now that you’ve launched the app, keep answering OK / Yes / Accept as can be seen in THIS screen. On the next screen, you’ll (again) press OK (the “Yes, but ask me next session” will be selected by default; it’s perfectly OK with us). After this, answer Yes to the next question too and, then, activate Accept to accept the license agreement.
Upon the first execution, after you click a link (and, therefore, initiate a network connection) you’ll need to press at least one button several times until the progress bar is full. You can do this with any button if you have numeric buttons; do this with the D-pad (any directions) if you don’t.
1.3 Usage
After this, you’ll find using OM pretty straightforward by using the two WM5 softkeys (or the touch screen). I’m pretty sure you’ll find it easy to use.
Note that in the review of the previous beta3, I’ve already spent a LOT of time explaining how link synchronization and managing RSS feeds work. Please do refer to the article for a complete overview of both these techniques.
Users new to OM will surely notice that entering text is done differently than using regular Web browsers. Now, if you click (move the focus to and press the Action button on it) a text input field / area, you won’t be able to do an “in-line” edit, but you’ll be taken to a separate and, in most cases, full screen text editor. Jbed’s text editor is one of the best (for comparison: TAO Intent’s (a well-known, widely used KVM) editor has severe restrictions: it doesn’t support copy/paste operations), but keep in mind that it (as with ALL the other KVM’s on Windows Mobile and some KVM’s on Symbian) can’t edit texts larger than some 4 kilobytes.
Note that after exiting (Menu / Exit) or shutting down (with an external task manager tool or by resetting the device) OM, you will need to go to Start / Programs and select the Esmertec Jbed icon (highlighted HERE) and click (or, press Launch while it’s selected) “Opera Mini” inside. Note that if you’re a somewhat more advanced user, you can easily invoke OM4 without starting Esmertec Jbed first (that is, you save some screen taps / button presses) by following my remarks in the “Direct, system-level links (shortcuts) to MIDlets” row of the main chart of the MIDlet Bible.
Under newer Symbian versions, you need to basically do the same as above. The difference is that these newer Symbian versions (as opposed to, say, the MIDlet Manager on the S60v1 N-Gage) puts a direct link to OM into Applications (example screenshot HERE); that is, you don’t need to create these links yourself.

1.4 Changes since beta 3
In addition to some, mostly “dumbphone” (that is, not Symbian / Windows Mobile-related) bug fixes, there is some welcome news for touch screen users.
First, you may already have noticed how complicated it is to reorganize the favorites list on the mobile phone. You repeatedly need to select Manage / Move up (or, down) to move a given favorite up or down, which involves a lot of work (and there’re no sorting capabilities built-in). Of course, if you have access to a desktop Opera browser, you can quickly do this stuff by either quick sorting (Sort / View by … in the context menu) or mouse-based drag and drop.
Now, if you have a touchscreen-based device (for example, a Pocket PC), you can, with the stylus, just highlight a favorite (as you would do when using the traditional way of reorganizing them) and, then, keeping the stylus down, drag it to its new position (note that this will not be animated – that is, you’ll only see the favorite moving after you’re lifted up the stylus from the touchscreen).
In addition, there’s another goodie you might want to know: now, keeping down the stylus on a Web page results in the context menu to be shown. The context menu slightly varies on the markup you’ve invoked it on:
links have a "Link" submenu, allowing for opening the link either with or without images (and also getting its address) as can be seen in HERE
images have a “Open Image” shortcut, which, in addition to showing the image in a new window, also let for downloading and saving it
the page itself (no links / images) “only” have the mobile view switch, reloading and information shortcuts
This context menu is also accessible by pressing “1” on the keypad - or, of course, emulating the keypress on the on-screen software input panel or, finally, assigned to a hardware button. This all has been thoroughly explained in the MIDlet Button Bible – make sure you DO read it because it’ll REALLY ease your life and increase your productivity.
Note that this all has also been (shortly) mentioned HERE.
The home screen also has some new links; for example, the brand new "GameJump" taking you to some freely available Java MIDlet games directly downloadable to your phone. They aren't particularly good; that is, don't expect anything like Gameloft or I-Play-like (see the links to the best Java MIDlet game developers at the end of MIDlet Bible!). I've tested three of these games on my N95: Arcade Park 1 (compared to the native PPC version, REALLY weak), CS Garfield (pretty OK but there're much better, albeit commercial bowling titles for Windows Mobile) and Spin Blocks (not worth bothering on devices with QVGA or larger screen because it uses 176*220). All in all, there's no free lunch; however, you may still want to look around for some games.
1.5 Frequently asked questions / misconceptions
1.5.1 Proxy servers and Opera Mini 4
Some people state (see for example THIS and THIS) the final version of OM4 doesn’t work with proxy servers any more, unlike with earlier OM4 beta builds. I’ve thoroughly tested this and found out that they do work assuming you explicitly switch the network access mode from Socket to HTTP (Menu / Tools / Settings / Network protocol).
1.5.2 Lack of code signing and the consequences
As you may already have noticed, Opera Mini is unsigned. This, unfortunately, means (depending on the actual KVM used and the operator restrictions / customizations) nagging screens when trying to access the Net. With Windows Mobile, you can “hack” the most widely used KVM’s, including the highly recommended Jbed. With Symbian, where the situation can be worse - again, depending on what additional restrictions are added by your mobile operator. Of course, you can always de-brand your device as is explained at, say, HERE.
You may also want to read THIS post (in THIS, pretty instructive thread) on why OM4 isn’t signed by default. (In a nutshell: the high price of the Verisign root certificate would have forced the developers of OM to make their browser commercial.)
I hope someone will be able to come up with a signed version of OM4 that works on at least Windows Mobile (with Jbed at least) and / or Symbian phones.
1.6 Recommended links
Please DO read the articles linked above; most importantly, the MIDlet Bible. It explains a LOT you might not ever have thought of. You will find it REALLY useful. If you do want to use Opera Mini to its full potential, you MUST read it and all the related tutorials (for example, the one on button handling, which is of extreme importance with OM4).

My W3C speech on Web browsing + a full explanation

As has been announced some weeks ago, I had a W3C speech a week ago devoted to Web browsing on mobile devices. You can find the (English) slides HERE. (Sorry, some of the example screenshots are in Finnish. This, however, doesn’t have a detrimental effect on the overall understandability of the material.) In order to understand the slides, I’ve also decided to comment on all of them so that the entire Windows Mobile, Symbian and BlackBerry mobile community can benefit from my speech – in written form. Finally, note that, albeit this article is over 80kchars long, it in no way can provide a FULL, absolutely thorough overview of the Web browsing scene on these platforms. That is, if you don’t understand something, don’t despair: in my referenced, previous articles, you can, in most cases, find a very thorough dissemination of the subject. Just an example: in this article, I only devote some 2kchars to the subject of downloading files while my original, devoted article, along with its (recent) updates, amount to over 100 kchars.
I also provide in-line screenshots in this article so that you know what I'm speaking about without constantly switching to PowerPoint; however, to see the original document at its full (and copy/pasteable) glory and resolution, you'll need the PPT file.
(Sorry for the comparatively bad quality – captured from the 1024*768 M-JPEG video(!) recording of my Canon 960IS camera.)

(just some self-promotion )

(Promoting my employer and me. Incidentally, should you want to support my employer - and, through that, me - with a, say, contract for some kind of development or any kind of IT consultation [if you work for a company that would like to outsource some kind of consultation or quality (!!!!), in-depth research], feel free to contact me and I’ll make sure my employer contacts you back. Even a, say, US$ 50,000 project would be welcome. I’ve been a generic – not just mobility! – IT consultant and lecturer [for example, for Sun’s Java training courses], but am also well versed in traditional Electric Engineering stuff like telecommunications and signal processing; see for example my forthcoming Digital TV / Telecommunications Bible for more info on the latter. That is, I’m in no way a mobility-only type of professional. In e-mail [werner AT pocketpcmag PISTE com, where change AT to @ and PISTE to . (dot)], I’m also ready to provide you with a more thorough list of past IT consultation, education etc. projects. It’s me that would be working on these contacts; together with an English editor to get the English right. I only expect serious inquiries. Please, if you like my articles and would like to see similar articles come out in the future too [it’s mostly because I have a lot of free time and a really cool environment at work that I am allowed to work on articles even during work hours], look around at your company to see whether there’s some way of outsourcing your, say, consultation, education or research needs. International contracts [on which I/we’ve worked several times] are welcome.)
OK, let’s get to business. Given that in a 45-minute speech it’s entirely impossible to give the listeners a complete, detailed picture of the problems, the compatibility issues of each and every browser for all the three operating systems, I’ve added references to all slides (whenever applicable). To quickly look up the referenced article / Bible, just change “1327” in http://www.pocketpcmag.com/blogs/index.php?p=1327 to the number given after „Ref:“
Also, you’ll need to be aware of three articles not (always) linked as references. The two Windows Mobile Web Browsing Bibles have the reference number 1828 and 2084 for Pocket PC’s and MS Smartphones, respectively. They, therefore, translate to real URL’s http://www.pocketpcmag.com/blogs/index.php?p=1828 and http://www.pocketpcmag.com/blogs/index.php?p=2084 . My Opera Mini 4.1 (Ref: 2571) review, which is currently not discussed in either of the Web Browsing Bibles, is worth checking out for the latest information on this excellent browser. Also, you can find all my Web browsing articles in the Web Browsers category on my blog at http://www.pocketpcmag.com/blogs/index.php?blog=3&cat=61
There are several established mobile operating systems (platforms). In this slide, I quickly list them. Of course, this is just a very high-level overview of the operating systems; it’s later that I elaborate on them more thoroughly; one by one.
Web browsing-wise, probably the most advanced platform is Windows Mobile (WM for short), which itself has basically two, starting with WM5, converging subplatforms: touchscreen-enabled Pocket PC’s (PPC for short) and touchscreen-less MS Smartphones. In WM6 parlance, they’ve been renamed to Windows Mobile 6 Professional / Classic and Windows Mobile 6 Standard, respectively. I’ve also listed Handheld PC’s for completeness (and as an introduction to the slide explaining the evolution of the built-in Web browser pre-installed on WindowsCE devices in the past 11.5 years), which are a dying breed.
Symbian is another, very important, consumer-focussed mobile operating system. The most featureful browser for its most popular breed, Nokia’s Series 60 (S60), is the Nokia S60 Web. They are, in addition, also able to run Opera Mini and other MIDlet-based browsers. It also used to have an Opera Mobile port, as was the case with some Linux-based models like the Sharp Zaurus.
RIM's BlackBerry is a very important business (and, with the advent of more consumer-friendly models like the Curve and Pearl and the, particularly multimedia-wise, really enhanced 4.5/4.6) operating system. Its Web browser has traditionally pretty bad. With operating system version 4.5/4.6, however, it has undergone a major facelift and received a lot of new features. For example, now, searching for text in pages works. This highly useful feature is only supported by very few other browsers – for example, it’s only been introduced to the two Opera browsers this year.
The hugely popular Apple iPhone runs Safari. It’s really a decent browser. The only real disadvantage is the complete lack of, for example, Flash (Lite) support. As YouTube (one of the major usage areas of Flash as of today) has a dedicated YouTube client, this isn’t that big a problem. Note that, unlike with the first three operating systems (and like all the following ones), I don’t elaborate on this operating system in the rest of my speech. Currently, iPhone doesn’t have Java MIDlet support; therefore, you won’t be able to run Opera Mini on it. Java, however, will be - hopefully - soon added.
Linux, after the, unfortunately, discontinued, but, technically, really-really excellent Sharp Zaurus series, seems to have been reborn: Nokia's Web Tablets and the non-Nokia phones based on the LiMo foundation’s operating systems are gaining popularity. Note that, as far as the old Zaurii are concerned, it had both Opera Mobile and NetFront (NF for short) preinstalled.
Finally, the once market-leading Palm OS is pretty much dead now; this is why I don’t elaborate on its (compared to what is available on Windows Mobile, iPhone and Symbian, not very advanced) browsers like the, with newer versions being NetFront-based, Blazer at all. Unfortunately, the only MIDlet manager (an environment to run Java-based applications like the Opera Mini browser) for the operating system is IBM’s now-discontinued J9, is really buggy and crashes frequently; this means you can’t even use Opera Mini on the platform.
First, let’s take a closer look at Windows Mobile and the core operating system, WindowsCE, paying special attention to how the built-in browser was enhanced during the 11.5 years of maturation.
With WindowsCE 1.0 (Handheld PC), which was released in early 1997 and used on several models like the HP 300/320LX, the Philips Velo etc, has only a really basic (no frames) but already online (non-offline) browser. (We’ll soon see why I emphasize it being online.)
The next two major releases of the operating system, WindowsCE 2.0 and 2.11 (released early 1998 and 1999, respectively) has gone in two directions to cater for people wanting a really palm-sized and, to keep the size down, keyboard-less version of the, compared to the, then, like-hot-cakes-selling Palm handhelds, not really popular WindowsCE models. The new form factor was named Palm-size PC (PsPC). Several WindowsCE hardware manufacturers released PsPC’s; for example, Casio released the Cassiopeia two-digit series (E10 etc.); Philips released the Nino, HP the Jornada 430 which was even featured in a James Bond movie etc. These devices only offered offline browsing; that is, if you had any kind of Internet connection on them (via, say, an infrared connection to a mobile phone), you still couldn’t directly access any Web pages. Instead, you needed to use the desktop based ActiveSync tool (earlier called as WindowsCE Services) to fetch the pages for you and synchronize it to your handheld for offline viewing.
It was only in the “traditional” Handheld PC handhelds, for example, the HP 360LX/620/680 (with the OS version 2.11, called Handheld PC Pros) that still had online access capabilities with a hugely enhanced and updated Web browser much better than the one in WinCE version 1.0.
The market’s answer to the 2.x-series handhelds was pretty much lukewarm. This also resulted in several manufacturers like Philips leaving the scene for ever. It was not before mid-2000, with the release of WindowsCE 3.0 and its hugely popular Pocket PC platform (a heavily enhanced version of the PsPC platform, fixing a lot of issues like the lack of online browsing support) that anyone would say WindowsCE-based handhelds would seriously endanger the market penetration of Palm handhelds and BlackBerry messengers.
WindowsCE 3.0, which was released in May 2000, was the first really successful MS mobile op. system. As with the 2.x series, two operating system subversions were based on it: the, technically, much more advanced (for example, its built-in browser was already capable of finding text in pages, which the Pocket PC version isn’t even now capable of) Handheld PC 2000 (HP 720/728 etc.) using the traditional clamshell form and the descendants of Palm-size PC’s, now, renamed to Pocket PC’s. The latter received an online Web client again; at the time, it was clearly less capable than that of the Handheld PC 2000 OS. Ironically, the latter operating system has practically died out pretty soon and now (its descendants) is used in niche models only.

Let’s go on with the Pocket PC operating system and its built-in browser, Pocket Internet Explorer (PIE). This was, incidentally, renamed to Internet Explorer Mobile (IEM) in 2005 with WM5.
In late 2001, the first version of the PPC OS (also called Pocket PC 2000) was updated to PPC2k2 (2002). While it did have certain advantages over the old operating system, Web browsing-wise it was more of a step back in speed / memory handling because it was incapable of rendering larger (about 150+ kbytes) pages – unlike its predecessors and successors.
In Spring 2003, Windows Mobile 2003 (WM2003 for short; notice the operating system name change!) followed with a much-much better built-in browser with, among other things, CSS support added. (Previous browsers didn’t at all support CS sheets.) Then, in Summer 2004, WM2003 Second Edition (WM2003SE) followed suit, with the native One Column mode being the most important enhancement (on which I’ll elaborate later), Web browsing-wise.
In Autumn 2005, WM5 arrived, also renaming PIE to IEM. It contained a heavily bugfixed IEM engine – some CSS contructs no longer result in the prompt termination of the PIE session, unlike in WM2003(SE). It was also the first PIE (IEM) version to support file uploading – a painful omission from previous PIE versions.
WM5 (and subsequent operating system releases) was also unique in that internal updates during the lifespan of the operating system were well-documented and referred to, easily checkable by an end user, via “AKU” versions. Just some major enhancements: while the initial WM5 IEM browser was pretty very slow to load Web pages, AKU 2 has fixed this almost completely. AKU3.5 introduced a High-Resolution switch for high-resolution VGA devices – another long-demanded feature.
In Spring 2007, WM6 followed suit, with no real improvements except the support for IFrames. Finally, this (2008) Spring, WM6.1 was announced with no real improvements either; a fully revised and enhanced version (a full port of the desktop IE6 engine) is promised later this (2008) year.
Speaking of the built-in browser, it still is pretty much incapable when compared to alternative browsers like Opera Mobile or even Mini. This is why there exist several so-called “plug-ins” or, with some less popular solutions, “shells” to enhance its functionality by adding, for example, multi-document (multitab) support. The most important plug-ins are as of today: Spb Pocket Plus, PIEPlus and MultiIE.
In the rest of my presentation, I’ll return to the compatibility issues of IEM several times; for the time being, let’s check out the other, alternative browsers.
In addition to PIE / IEM, there are several third-party browsers on Windows Mobile. Let’s start with standalone, native Windows Mobile ones (native means you don’t need to run them in a specific environment like a MIDlet manager). The first group is non-streaming too, meaning no excess data fees over a non-flatrate connection / inability to use over non-3+G connections.
* Opera Mobile: probably the most important Web browser. It’s, more or less, based on a direct kernel port of the desktop engine, meaning excellent compliance with core Web standards. Note that the currently, officially available version, 8.65, is still based on the 8.x core; it’s only the latest, 9.x-series Opera Mobile that have, finally, switched to the 9.x core and delivers full compliance with all current standards. While it’s a fairly new browser (the first beta was released in early 2006), it’s taken the Windows Mobile Web browsing scene by storm and is the preferred Web browser of many.
* NetFront is a long-established browser. Unfortunately, while it does have its merits, the development seem to have slowed down and several major bugs haven’t been fixed for years. (For example, you still need to rely on the definitely inferior built-in Flash interpreter instead of having the ability to use external, official and much better-quality Flash plug-ins.) I really hope Access, the developer of NetFront, finally starts to make some serious enhancements to this browser.
* Thuderhawk: this is another long-established browser. The classic (native Windows Mobile) client has received no real improvements in the last about two or three years (except for adding Java applet support back in 2006) and it seems it’s completely abandoned as the company is switching to a MIDlet-based and, therefore, truly multiplatform (not only WinMo) solution.
* Minimo, which is an unofficial and, now, abandoned Mozilla Firefox-port. Unfortunately, I can’t really recommend this browser – its speed, performance and memory consumption is pretty bad when compared to most of the alternatives. Note that it has nothing to do with the real, official Windows Mobile Firefox port announced some months ago.
* Picsel’s browser is an OEM-only one and, therefore, can’t be acquired (legally) if it isn’t included in your factory ROM. It’s pretty slow and is incompatible with even basic Web standards. Nevertheless, some people still like it.
* Maximus: it’s a really poor and in no way recommended browser.
Streaming-based but still native browsers follow. The most important of them is SkyFire which, currently, only works in the 3G networks of the U.S. As I’m in Europe, I can’t really give it a thorough ride at the moment. Another, similar (but, based on the raving user reports on SkyFire, speed- and usability-wise, really inferior) solution was Microsoft’s DeepFish, which has been discontinued in the meantime. Also note that there are other, streaming-based, dedicated mobile solutions like DataWind’s PocketSurfer 2.
Finally, let’s elaborate a bit on MIDlet-based browsers. Their biggest advantage is the compatibility with all other mobile platforms, including even “dumb” feature phones (but excluding BREW-only dumbphones used in some American networks). This will even include the iPhone as soon as Sun (and Apple) gets their MIDlet manager, the environment you can run MIDlets in, ready. Their biggest disadvantages are
1. the somewhat reduced speed. In practice, however, you won’t really notice this; the only real difference is the download speed when you use the in-process download manager, as opposed to using the system-level Web browser to download files. As you will want to prefer the latter, this isn’t an issue.
2. the lesser integration with the operating system. For example, you can’t copy arbitrary text from Web pages. This can be done in a very awkward way with Opera Mini 4.1: save the page to a file and inspect the saved file (containing the Web page in a textual, albeit non-HTML form) with a copy-capable file viewer.
Another major issue is the inability to make the browser the default one for the entire system – at least for non-Windows Mobile operating systems. On the latter, thanks to me and two other developers, this is already possible, making your life much easier: you can now just click links in a, say, e-mail and Opera Mini (or, alternatively, any other Java MIDlet-based Web browser) opens the given page.
Of the MIDlet-based (non-native) browsers, it’s Opera Mini that is the most important. Now, as of version 4.1 and all its new goodies (like file upload and page saving), along with our direct invocation tools, it’s a serious alternative to fully-fledged, non-Java-based browsers.
Some other MIDlet-based browsers include TeaShark and UCWEB. The brand new version of Thunderhawk (TH for short) is also Java-based but is strictly OEM only and isn’t available for the general public.
BlackBerry from RIM, as has already been pointed out, is mostly a business “push mail” platform, only recently opening its gates for the consumer wanting more multimedia and camera. Officially, it’s still at OS version 4.2 / 4.3; the new version, 4.5 / 4.6, is slated to be released in a few months. In the meantime, you will really want to check out the (largely unofficial) betas as they offer a lot of goodies seriously enhancing the usability, user- and, through the new fontsets, eye-friendliness of the platform.
In the two screenshots at the bottom of the slide, you can see how the old, 4.2 OS (on the left) rendered the first few entries in my Opera Mini favorites list and how the same is done under 4.5 (on the right). As can clearly be seen, under 4.5, much more contents can be displayed on the screen and the fonts are much better-looking and readable.
As far as Symbian is concerned, there used to be several subversions of Nokia’s Symbian. (Here, I don’t elaborate on Sony-Ericsson’s handsets.) Of them, S60 is the surviving one and the once-common S80 and S90 versions are both dead. A major breakthorugh, touchscreen, will be added this or next year and Nokia is promising an iPhone killer, Nokia Cube.

S60’s later versions (namely, ones that represent the 3rd generation of S60, S60 3rd, and come with Feature Pack 1 (FP1) or [in the future] higher), have an excellent built-in Web browser, Nokia S60 Web. It’s based on WebKit, an excellent core to build Web browsers on. It also supports Flash Lite 2 and 3; the latter has been delivered in firmware updates (v21 for the N95) and not as standalone downloads. Flash Lite 3 is much better to play back YouTube / other videos than the full Flash 7 on Windows Mobile.
On the screenshot on the right, you can see one of its major features, the minimap, in action. It helps in positioning on a page quite fast and is, now, widely copied by other browsers like NetFront 3.4+.
Now that we have had a bird’s view overview of what’s available on the three platforms (and, as far as Java/MIDlet-capable phones are concerned, - including, sooner or later, the iPhone - all of the other), let’s take a closer look at the issues a mobile Web browser can be confronted when browsing pages originally targeted at desktop (and not resource-restricted, dumbed-down mobile) browser users.
First, you need to consider architectural restrictions, the (comparatively) small amount of RAM (dynamic) memory (10...90 Mbytes on higher-end handsets; (much) lower on feature phones) being one of the biggest problem.
While you can, generally, build up the in-memory representation of even several kilobyte-long Web pages using less than 10 Mbytes, having restricted RAM severely restricts the handset’s ability to store multiple Web pages in-memory for quick access without having to re-fetch (re-download) them. Note that dynamic memory consumption-wise, I really recommend my thorough RAM usage tests in the Web Browsing Bible.
Different Web browsers certainly have vastly different memory needs; this is why, for example, Opera Mini 4.1 is able to keep up to 30 pages in memory even on devices with little RAM. Opera Mobile consumes about an order of magnitude more memory, but is still about two two three times better than IEM, NetFront or Minimo.
The CPU efficiency (a 624 MHz Intel / Marvell XScale is equivalent of a max. 200-300 MHz Pentium) can also be an issue, particularly if you provide dynamic content. While Java Script and Ajax (if it’s compatible at all) run pretty OK, the case isn’t necessarily the same with embedded Flash content, particularly on Windows Mobile platform, where the current, official Flash 7 plug-in is pretty slow. (NetFront’s own Flash interpreter being even worse.) As a rule of thumb, you should use Flash Lite 2 or 3 instead if you want flawless, fast execution. (Currently, Flash Lite 3 is supported by Symbian only and Windows Mobile is slated to introduce support only later.)
On mobile devices, cache reading / writing can also be about an order (or even more) of magnitude slower than on a desktop / notebook hard disk (1-2 as opposed to 20-40 Mbyte/s being typical). This means far higher page loading times if the particular browser employs a bad caching algorithm. (I’ve also very thoroughly elaborated on all these issues in the Bible; the reader is referred to it for more info.)
Multitab browsers may also be affected by the process number restrictions under pre-Windows Mobile 7 (that is, all current) operating systems. This will mostly result in issues with multitab browsers spawning an entirely new process for each and every tab (all IEM plug-ins work this way); that is, not with, say, Opera Mini.
Finally, "from stratch" browsers (that is, browsers that aren‘t direct ports of any established desktop Web browsers; some examples are NetFront, Thunderhawk, UCWeb etc.) generally suffer from severe bugs / errors on even the HTTP protocol level, let alone higher-level HTML / CSS bugs.
Let us still elaborate on the question of what a mobile browser can be used for. As has already been pointed out, their biggest advantage on all mobile platforms is the fact that you aren’t restricted to specially formatted PDA/handset-only pages like WAP pages and you can access full pages initially meant for desktop users. This makes it possible for you to access orders of magnitude more pages than some 5-6 years ago with feature (dumb) phones’ only able to access WAP pages.
However, as has already been explained in the previous slide, you need to be avare of several possible problem areas when accessing an initially desktop-optimized page.
* First, >500k HTMLs (for example pages generated by Snitz Forums 2000 or even YouTube) may result in a severe slowdown or even crashes on the client; under Windows Mobile, particularly under the PPC2k2 operating system, which, as has already been explained, only allows for rendering max. 100-120k HTML pages without crashing
* As has already been explained, under IEM, the memory usage is about an order of magnitude more than the original size of HTML. With alternate browsers (particularly with Opera Mini and, to a lesser degree, Opera Mobile) this isn’t an issue.
* (Desktop) ActiveX controls are not supported, not even on Windows Mobile because it’s not an x86 architecture and, therefore, can’t run native x86 code.
* Some browsers (IEM and, particularly, Thunderhawk and Picsel) have very weak JavaScript support
* Unfortunately, Java applets (login, authentication) are only supported by custom third-party JVMs only. What is more, it’s only available on Windows Mobile – that is, there’s no applet support at all on Symbian / BB. On Windows Mobile, applet support is pretty restricted and is only compatible with up to JDK1.4 (unless you use Thunderhawk). There's no official support from Sun on these three platforms either, unlike on iPhone.
* I’ve already mentioned the Flash incompatibility and problems and the less important HTTP/HTML problems, bugs and restrictions.
On slide 8, I’ve already elaborated on the different networking models used by Web browsers, as far as client-middle tier server streaming-based vs. standard, middle-tier-less browsers are concerned. A nonstandard setup can be vastly different from the pretty much bandwidth-hungry streaming-based solution, however. On this slide, I further elaborate on this distinction.
Most online (as opposed to offline; see for example AvantGo, Mobipocket Reader or iSilo offline web downloading and ActiveSync-based syncing to the handset) browsers use direct connections.There are, however, clients that do have a (sometimes simplified) client-side textual (!) renderer component – as opposed to traditional streaming clients (SkyFire, DeepFish and specialized hardware like PocketSurfer 2) – don’t consume much data. On the contrary: one of the design goals of these clients was to vastly reduce data usage, which is of paramount importance with non-flat rate connections - like those of Canadian mobile operators - and make them usable even over super-expensive, typically, 3...5 Mbyte/month BlackBerry data plans. That is, they work in exactly the opposite way as data-hungry apps like SkyFire and deliver considerable data saving even when compared to accessing the same Web pages with a standalone client.
The most important of these client/server browsers, making use of (pretty much) transparent proxies, are Opera Mini (and most of? all? the other MIDlet-based browsers) and Thunderhawk.
These solutions have some drawbacks:
* possible eavesdropping (definitely not the case with Opera; as far as some new, “noname” Chinese browser companies are concerned, however, many believe that the opposite is true; as a rule of thumb, never ever enter any credit card info in any of these new and pretty much unknown browsers)
* they are not flexible enough – there’s no way to use other proxies like the highly useful header rewriter proxies to allow for, say, asking for nationalized versions of pages (more on this later)
* sometimes introduce a definite delay because the (sometimes overburdened) middle-tier server has to process the source pages themselves. With Opera Mini, the delay, typically, ranges from 2 to 30 seconds – that is, sometimes it’s on the verge of acceptability.
* Some incompatibility issues with some sites; for example, the current Opera Mini 4.1 is not compatible with the “Quote” button in vBulletin version 3.6.8 currently used at, say, forum.xda-developers.com.
Some of the pros (much less data overhead) have already been mentioned; on top of that, what you gain is also anonymity. That is, your real IP is hidden – the Web page you access sees Opera’s middle-tier server as the client, not your own IP. Note that your IP is told to the Web server but in an extended HTTP request header, which few of these servers log.
Now, let’s turn our attention to IEM, that is, the browser coming with built into the Windows Mobile operating system. As has already been explained, it has pretty weak and, with standard Ajax, plain non-existing Ajax/JavaScript support. Its CSS support is equally bad. It doesn’t support the multidocument model (which was introduced in IE7 on the desktop) support without 3rd party so-called “plug-ins”. It’s also pretty much limited in that it has no link target / current page saving capabilities (which are pretty much essential).

The same used to apply to image saving in operating system versions prior to WM5. Also, it has severe restrictions like absolutely no IFrame support in pre-WM6 versions and only supports displaying 12 (in WM6) and 10 (in pre-WM6) frames. In this regard (too) alternative, commercial browsers fare far better.
Its stability used to be pretty bad in pre-WM5 times too: it frequently crashed because of certain CSS constructs. I’ve found and published several such CSS constructs back then. This is, fortunately, no longer the case in WM5+.
The two screenshots show how the mobile version of the PPCMag blog and the desktop version of YLE’s (Finnish Broadcasting Company) main page is displayed on a high-resolution VGA device.
Historically, on high-res Windows Mobile models, IEM had the “pixel doubling” problem, meaning images were still rendered as low-res, with double their size. This was fixed in WM5 AKU 3.5 (in early 2007), which lets the users switch between “High-resolution” and the default standard mode. This, however, didn’t really help external applications making use of the IEM rendering engine to display HTML-formatted contents like CHM readers – they still render images with pixel doubling (and, unfortunately, charts too) on high-resolution devices.
Incidentally, when used as a plug-in, there is another source of problem. If you don’t close HTML tags right after the (last) word like in <i>foo </i>bar (as opposed to <i>foo</i> bar), then, the two (formatted and the next) words will be rendered without a space in between them. In the two screenshots presented in the article (a low-res QVGA and a high-res VGA one), I show the results of this “bad-formatted” construct. Note that in the expression “fox jumps over a lazy dog”, ‘fox jumps’ is rendered as one word only because its HTML source was like this: “<b>fox </b>jumps over a lazy dog” and not the recommended “<b>fox</b> jumps over a lazy dog”.
Let’s turn our attention to NetFront, a well-known commercial browser for Windows Mobile. While it’s a bit expensive ($30), it offers an excellent browsing experience – except for some (rather major) problems and bugs. For example, it has built-in Flash support, which is, unfortunately, weaker than that of Adobe / Macromedia used by both IEM and Opera Mobile (it has compatibility issues and severe CPU usage problems). It supports SVG (which is very commonly used in Japan’s 3G content networks) and also has a Java VM to run applets. The latter, unfortunately, is definitely weaker than that of CrEme, the best JVM available for Windows Mobile and, in cases (where there isn’t much animation / graphics involved), even the Java support of the traditional, non-MIDlet-based Thunderhawk. It supports multitabs but their number is, unfortunately, maximized (to five) – as opposed to IEM plug-ins, Minimo or the Operas. I just can’t understand the rationale for this restriction; after all, on a modern 128 Mbyte RAM device, dozens of Web pages can be stored in RAM for quick access / swith. It also has minimap support and, which is very important for many iPhone fans, iPhone-like acceleration when dragging the screen contents by a finger / the stylus.
It has, as of version 3.4 and 3.5 (not NOT previous versions!), has pretty good Ajax/ JavaScript/ CSS support and its rendering engine is definitely better than that of IEM.
The recent releases are as follows: 3.3 (Summer 2006; inferior); 3.4 (Fall 2007): OEM only; currently: 3.5 Technical Previews. This, unfortunately, means you can only get the outdated and (compared to later 3.4 and current 3.5 versions) pretty much incapable 3.3 if you plan to go for this browser. Unfortunately, the currently available 3.5 Technical Previews versions are pretty much limited: no more favorites than 10; no Java / Flash support; no more tabs than 2. In this regard, Opera Mobile and most IEM plug-ins with their 30-day unlimited trial is much better. I hope the NetFront developers consider this and unlock all the features of future Technical Previews, only leaving a timebomb in rendering the browser useless after a certain date. (Noone will set their clocks back – and suffer from the consequences – just to be able to run NetFront to save $30.)
Now, let’s take a deeper look at Minimo, the free and, unfortunately, discontinued (cancelled), unofficial Firefox port. Note that the already-announced official Firefox will be later released for Windows Mobile; currently, no release date is known.
It comes in two versions: 0.16 (for pre-WM5 devices) and 0.20 (for WM5+ only). It’s plain useless on some models because of speed problems and other bugs. On the ones that it doesn’t have model-specific problems, however, is a semi-decent alternative if you really want a free browser other than Opera Mini.
Being based on the Firefox engine, it has excellent scripting (including Ajax) and CSS support. Not as good as Opera Mobile 9.xx, though.
Now comes without doubt (as of version 9.xx) the best, fastest and most powerful standalone Web browser, Opera Mobile. It has excellent JS / Ajax support, almost 100% compatibility with all Web standards, particularly with version 9.33; it’s very fast at everything (loading pages, downloading files etc.), supports the standard Adobe / Macromedia Flash plug-in (unlike NetFront, which forces the user to rely on the built-in and definitely inferior Flash engine) and lets for opening any number of tabs, as opposed to NetFront or IEM without a plug-in. It (as of version 9.xx – but, unfortunately, not the currently commercially available 8.65) also has some other goodies like finding text in pages, which is not available in any IEM-based solutions, not even commercial ones.
Currently, it’s available in two versions: the official (8.65) and the preview (9.33 / 9.5), for both PPC’s and Smartphones. The latter, 9.xx-series has without doubt the best standards compliance of all browsers for Windows Mobile.

Opera Mini, as of version 4.1, has become a really-really decent alternative to other Web browsers, particularly if you need a free solution. As it’s a MIDlet, it’s compatible with almost every phone out there – even feature phones. This means you get exactly the same menus, the same shortcuts on, say, your wife’s low-end feature phone and your smartphone.
It requires a separate environment, a MIDlet manager, to run. I’ve elaborated on the different MIDlet managers available for Windows Mobile in the MIDlet Bible, which you definitely should read if you want to get introduced to the wonderful world of MIDlets. (Note that you won’t necessarily need to read it if your only aim is to be able to install and use Opera Mini 4.1; then, all you’ll need to do is reading my 4.1 deployment and usage tutorial.)
As of the current (4.1beta) version, it offers even file upload, address autocompletion and page saving capabilities. Full page view is also supported (which has been added in version 4.0), retaining the full layout of the original page - as opposed to the one-column view. Incidentally, it’s this that you can see in the above screenshot too.
Its only problem is the lack of arbitrary text copying from Web pages. This could easily be fixed as is done in Russian Opera Mod (an unofficial and, unfortunately, illegal modification of the original Opera Mini) – feeding the textual page contents to a text input area, where it can already be copied to the clipboard if the particular MIDlet manager allows for this (all of them do on all the three reviewed mobile platforms; the only exception is the discontinued and outdated TAO Intent MIDlet manager on Windows Mobile).
As it’s a proxy-based solution, it has far less data usage; however, it can’t access local files (files in the file system) and the additional processing can take some time (typically, between 5 and 30 secs).
Thanks to extensive hacking, direct invocation has also been implemented (originally by me), which greatly enhances its usability on Windows Mobile because it lets for being directly invoked when you click a link in an e-mail or Office document. This isn’t as important on Symbian and BlackBerry because it’s far easier to copy / paste e-mail links in these operating systems (when you step over a link, it’ll be highlighted at once; then, you can copy it to the clipboard at once [as opposed to the, in this regard, much slower and more awkward Windows Mobile]; pasting to Opera Mini’s address input field is equally easy and quick), should you want to avoid using their built-in, respective browsers (for example in order to keep data usage down.)
Finally, still on the subject of Symbian and BlackBerry: while all public builds of version 4.0 frequently (about once a day) crashed on these platforms, I haven’t ever encountered any crashes with 4.1. That is, you won’t ever need to remove and reinsert the battery in order to reset your handsets.
Thuderhawk has a long history on Pocket PC’s. (It also had a MS Smartphone-compliant version, but only for low-res, 176*220 screens, and a QVGA version has never been released for this platform.) Unfortunately, it also seems it’s no longer worked upon as the developer has entirely switched to a MIDlet-based solution to directly compete with Opera Mini. (Which is more than hard as Opera Mini is really-really good.)
Thuderhawk’s biggest advantage has always been it being based on its own fontset (BitStream is also a font designer company), which makes original-layout, full page rendering possible even on 320-wide (QVGA) screens by using special, narrow, but perfectly readable fonts not otherwise available under Windows Mobile. Note that IEM can use similar fonts to look pretty much the same condensed as is explained HERE; the lower right screenshot shows exactly this, while the upper one shows a typical forum page rendered on a 320-wide screen without any need to do any horizontal scrolling.
Unfortunately, being based on a custom fontset means Thunderhawk only supports Western characters; meaning no support for most Eastern European or oriental languages. With Eastern-European, non-cyrillic languages like Polish, Romanian, Hungarian, Czech, Slovakian, Slovenian etc. that use alphabets pretty close to Western languages, this can be somewhat fixed by converting their special, Unicode-only characters to 8859-1 on the server side; with fully Unicode languages, on the other hand, this can’t be done.
Thunderhawk has no support for hi-res ((W)VGA) screens (it displays contents at QVGA effective resolution); doesn’t let for any kind of page / link target saving at all and doesn’t even support copying to the clipboard from Web pages. It doesn‘t use client-side web page / image caching at all (meaning, at times, it may result in far bigger data usage than most of the alternatives); it is only able to download files to built-in storage (not to storage cards or other, alternative media); it has absolutely no support for file upload etc.
Microsoft Deepfish should also be mentioned, which was more of a pilot project slightly more than a year ago to see how server-side content rendering with plain image-based client-server communication works. It wasn’t anything to write home about: because of the client’s being based on the (comparatively) slow Compact Framework and the middle tier server’s being overloaded, it was pretty slow in real use. It’s been discontinued in the meantime. It’s still not known whether it’ll be reused in future Microsoft browsers – for example, in the IE6 port slated for later this year.
Now, let’s take a look at the IEM plug-ins, which greatly extend the functionality (but, alas, not the Web standard compliance / conformance) of IEM.
These plug-ins greatly extend IEM’s capabilities: they add multitab (multiple document) support, resource (page / link target / image) saving, User-Agent GUI-based setting; they let for using hardware buttons for much easier navigation / function access, address bar macros, altering the way the document is scrolled by D-pad etc.; some of them even have GPS-based, location-dependent services.)
* PIEPlus is probably the best and most featureful (resource saving, support for hardware button reassignment etc.). For pre-WM2003SE users (“One Column” was only introduced in WM2003SE), it has a unique feature not offered by other PIE plug-ins: the Pocket View one-column view
* MultiIE is also a decent IEM plug-in; albeit, it’s in no way better than PIEPlus any more (unlike in the past). Basically, it has a similar feature set as PIEPlus.

ftxPBrowser: this PIE plug-in (or, more precisely, a shell), in pre-WM5 times, used to be highly recommended. As it’s mostly incompatible with WM5+, it’s not recommended any more.
Webby, another shell (not a real plug-in), is .NET Compact Framework-based and is, therefore, a bit on the slow side. However, it’s become better and better over time and offers for example extensions like Mozilla for for example ad filtering. It doesn’t let for accessing some of the features of the underlying IEM; for example, it has no One Column mode.
The brand-new Touch Browser, which tries to mimic Safari on iPhone, is pretty similar to Webby in that it’s another CF-based shell. The initial versions were pretty bad; hopefully, future versions will, hopefully, improve on the situation.
Finally, Spb Pocket Plus 4 should be mentioned (see screenshot on the same slide, showing its tabs). While before version 4 it was definitely worse (it didn’t even offer on-screen, easily clickable tabs) than PIEPlus or MultiIE (the two major alternatives), this is no longer the case: version 4.0 has fixed this, along with other goodies like accelerated screen dragging just like on the iPhone.
Now that we’ve seen the major browsers (and plug-ins) for the three operating systems, let’s quickly elaborate on what problems running them under Windows Mobile may result in.
The most important of them, particularly under pre-WM5 operating systems (particularly under WM2003SE), is the driver memory usage, which rendered NetFront and Opera Mobile unable to start under certain circumstances – unless you reset the entire handheld.
Let’s go on with discussing the different client-side techniques helping in reformatting (“reflowing”) a page to (horizontally) fit in a low-resolution screen. If we don’t do this, the low (horizontal) screen resolution (240 by default - 320 when used in Landscape -; some low-end MS Smartphones and pre-v3 Symbian S60 Smartphones had even worse-resolution (176*208 / 220) screens) results in having to scroll horizontally. This is why there are several “One column” client-side implementations. (There’re also middle-tier implementations like Skweezer; more on them later). On Windows Mobile, these special modes are supported by all browsers except Thunderhawk. On Symbian S60’s Nokia Web, in most cases, they are unnecessary as the browser is smart enough to be able to correctly re-flow text – as is the case in Opera Mini in non-one column mode. These two browsers are truly excellent in intelligently reflowing text.
In IEM, there’re (with WM2003SE+ devices) three rendering modes: the truly one-column “One column”, the “Fit to screen” (later renamed to “Default”), in addition to “Desktop view”. The three screenshots on this slide show an example BrightHand forum page in the Desktop / Fit to Screen (Default) / One Column order (from left to right).
Note that One column isn’t necessarily better than Fit to screen. There are cases when the latter delivers better results than the One column mode; for example, when you render simple charts (tables) not wider than 3-4 columns (or 6-8 columns in High-Resolution mode, if your handheld is a high-resolution one). Then, One column will display all the cells vertically, making the original layout completely messed up, while the Fit to screen mode will try to render them horizontally. However, in general, Fit to screen delivers results not needing horizontal scrolling in much fewer cases than Nokia Web or Opera Mini 4+ in non-mobile view mode, particularly on low-resolution (for example, QVGA) screens.
As, as has already been pointed out, pre-WM2003SE PIE’s, where there’s no One Column and the only “Fit to Screen” (Default) mode can’t correctly render the contents of the page without horizontal scrolling, you’ll need to use one of the following alternatives:
External Web compression / reformatting / one-columnizing services (Skweezer, Google Mobile etc.). They, unfortunately, get rid most of JavaScript code, making a lot of JavaScript-based functionality like changing pages in some forum engines inaccessible.
PIEPlus because of the explicit Pocket View mode, which fixes this problem
Use an alternate browser like Opera Mobile (WM2003) or Thunderhawk (compatible with even PPC2k / 2k2), which handle these cases much better
Wait for Touch Browser’s (which does have a built-in One Column mode) becoming much better

With Opera Mobile, the three rendering modes are almost the same as under IEM. It should, however, be pointed out that the One Column mode is buggy: the horizontal size is 240 pixels; that is, it’s only really usable on QVGA devices used in Portrait – preferably not in Landscape and definitely not on a (W)VGA hi-res model.
It, as has already been stated, generally fares much better in rendering blocks of texts without any need for horizontal scrolling. Just compare the first (leftmost) screenshot to the Desktop rendering screenshot of IEM: as can clearly be seen, this particular page was correctly (no need for horizontal scrolling) rendered by Opera Mobile in Desktop mode, unlike with IEM. (Of course, most of the time, you won’t want to use the Desktop mode, unless you need to see images in their original size, without being resized to fit the screen.)
The three screenshots, from left to right, show exactly the same three modes, in the same order, as with IEM: Desktop, Fit to screen and, finally, One Column. As the screenshots have been taken on a VGA device, the latter is buggy and only uses the left half of the screen.
Note that the One Column mode is clearly better implemented in Opera Mobile than in IEM (apart from the 240-pixel bug): it renders charts much better than IEM in One Column mode. See the example screenshots and discussion at the end of section 1.2 Opera Mobile of the MS Smartphone Web Browsing Bible.
NetFront has three similar modes: Normal, Just-Fit (about the same as “Fit to Screen” / “Default” in IEM and Opera Mobile) and, finally, Smart-Fit. The latter mode is without doubt the best: it’s like One Column, but still tries to render contents horizontally where applicable, unlike IEM and like Opera Mobile.
The three example screenshots (from left to right), as with IEM and Opera Mobile, have been taken using Normal, Just-Fit and Smart-Fit.
Minimo only has two modes: the default (desktop) mode and SSR (Small Screen Rendering), which is almost the same as One Column mode in the other browsers. The two screenshots show this (left: default, right: SSR).
Finally, in the Thunderhawk screenshot, you can see how well it manages to display even the most delicate screen contents without the need for horizontal scrolling. Note that it forces the user to use the horizontal orientation, which may be overly problematic on models with screen polarization issues in this orientation (as opposed to Portrait mode). However, users of devices with pre-WM2003SE operating systems (and a device without polarization problems) will surely welcome Thunderhawk’s using Landscape mode – none of the alternate browsers do so, not even the ones that, otherwise, could (as with some e-book readers like Mobipocket), not being based on IEM. (It was in WM2003SE that user-switchable Portrait / Landscape rotation has been added.)

Now that we’ve reviewed the browsers’ approach to rendering pages / textual page content originally designed for at least 800-wide screens on 176…640-wide screens, let’s turn our attention to other questions like (easily) controlling the browsers – for example, scrolling pages using hardware buttons.
There are several ways you can easily scroll a Web page up and down without using the touchscreen. The most common way of doing this is using the D-pad.
1. If you stick to using the D-pad, under IEM, by default, you’ll end up using link scrolling (as opposed to page scrolling). This can be a pain in the back, particularly on pages that have several links on them (you end up having to press Down several times to be able to scroll to new contents); fortunately, it can be altered on the Registry level (with a Registry hack). Most IEM plug-ins (PIEPlus, MultiIE at least) allow for doing this on the GUI level, making Registry hacks unnecessary.
Some browsers / plug-ins even allow for supplying the one-page-at-a-time scroll amount in percents. The screenshot in the slide shows exactly this with NetFront, where you can easily set this.
2. If you (also) utilize other buttons for at least page scrolling down, you can still use the D-pad for link scrolling (assuming you prefer one-handed use and don’t want to touch the screen to follow a link) by assigning the Page Down operation to any hardware button. This has thoroughly been explained in the Button Enhancer Bible.
3. Also, if you have a volume slider on your handset, you can use the jog dial / volume controller with the excellent SmartSKey utility; most of the browsers support this.
4. Under Settings / Buttons, you can also directly assign the “Page Up” and “Page Down” functionality to any hardware button (or, for that matter, even special buttons, jog dials and volume sliders with advanced, third-party button enhancer utilities like AE Button Plus.)
Note that, as far as Symbian is concerned, it Nokia S60 Web makes navigation pretty easy with its minimap accessed by pressing and holding the up/down button. So does the built-in Web browser with the latest, 4.5/4.6 version of BlackBerry. Finally, don’t forget that Opera Mini and Opera Mobile support page scrolling using the numeric buttons on phones that do have these – then, you can still use the D-pad to scroll link by link (or, if you use Mobile View [that is, One Column mode] with Opera Mini, left/right to scroll pages).
While certainly not as widely used as Flash content (any more), Java applet support is still nice to have – some (mostly internal and/or enterprise front-end) pages (still) use Java applets. For Windows Mobile, there are several solutions - Java Virtual Machines (JVM's). BB and Symbian have absolutely no applet support.
IEM depends on JVM plug-ins (as is the case with Flash plug-ins). Only two JVM’s have applet support (JVM’s with no Applet support are IBM J9 (it’s MIDlet / Personal Java only) and Mysaifu (it’s application-only)):
* Insignia Jeode; last version dates back to 2003 (came with the iPAQ 5550 – and previous iPAQ models. Most of these are locked to either the iPAQ brand or the given model). Today, as Insignia / Esmertec has stopped developing it (because they have moved to producing MIDlet managers), it can in no way be acquired legally
* CrEme: this is without doubt the best JVM to run applets. Unfortunately, it’s not meant for non-OEM customers, albeit they do have a downloadable 30-day trial on their homepage
Unfortunately, unlike with the Flash (Lite) plug-ins, Opera Mobile can’t make use of these plug-ins.
As far as the other browsers are concerned, the following two browsers have a built-in JVM:
* NetFront 3.1+: acceptable quality / compatibility (unfortunately, worse than Jeode / CrEme – as is the case with Access’ own Flash support in NetFront)
* Thunderhawk: in order to avoid producing a huge install (even older, non-fully-fledged Java runtime libraries easily add 1-2 Mbytes to the static size of the program [let alone newer JDK’s like 1.5+], which is pretty low – around 700 kbytes – with TH) and still provide full (!) JDK 1.5+ compatibility, the BitStream folks have gone for a strictly client-server solution, the server-side actively interpreting and executing the applet and just sending its GUI as a static image to the client. It, while it indeed offers full JDK1.5+ compatibility, has some cons compared to all the other solutions using local code execution: the images are low-res, slow-to-refresh and can cause excess data usage as the image of their GUI needs to be downloaded to the client every, say, second.
There’s absolutely no applet support in Opera Mini/Mobile or Minimo. In addition, currently, the WebKit-based browsers (Iris etc.) don’t support applets either - as with the Flash plug-in. Hope at least this changes in the future.
There’re some additional Web technologies that have become pretty standardized. You may have noticed Internet Explorer, Firefox or Opera don’t contain any kind of a Flash plug-in on the desktop Windows. The situation is exactly the same on mobile operating systems: few browsers or operating systems come with Flash support built-in (the two most important exception being NetFront on Windows Mobile and Symbian S60’s Nokia S60 Web with Flash Lite 2 / 3).
Flash being by far the most important additional technology requiring a plug-in (with most browsers), let’s take a deeper look at the Flash support on all these mobile operating systems. Let’s start with Windows Mobile.
IEM (all versions starting with PPC2k2) and Opera Mobile (as of version 8.65+) both have a somewhat restricted Flash 7 plug-in (and Flash Lite 2, in addition). It’s quite outdated and, of course, doesn’t support the latest technologies. It isn’t particularly efficient either; for example, its YouTube / other Flash video playback performance is plain sub-par.
NetFront has a built-in Flash engine, which is even inferior to the Flash 7 plug-in: it’s buggy, (even) less compliant and has major CPU usage bugs.
There’s absolutely no Flash support in Minimo, Opera Mini and Thunderhawk.
As far as BlackBerry, Symbian and the iPhone are concerned, they have absolutely no full Flash support. Symbian, however, supports Flash Lite 3 (depending on the model and the firmware used) – unlike Windows Mobile. Flash Lite will be discussed in the next slide(s).
(The screenshot shows the full Flash-based Bomberman, one of my favorite real-world Flash tester games, running in IEM.)
Flash Lite 3, which has recently been released for some past and recent Symbian S60 3rd edition models as firmware upgrades, has excellent support for YouTube and other, Flash-based Web video repositories. It’s, unfortunately, not available for Windows Mobile / BlackBerry / iPhone (as yet). For WM, it’s coming; for the other two mobile operating system, nothing is certain.
The two screenshots show Nokia S60 Web on the v21 firmware-based N95 playing back YouTube videos; the bottom left in Landscape (the video shrinked to the QVGA screen size); the one on the right on the original size in Portrait (hence the vastly oversized video). I haven’t provided similar screenshots on Windows Mobile because the Flash 7 plug-in on WM is very slow & inefficient and it’s almost impossible to use it to play back any Flash videos. Fortunately, a lot of alternative methods for playing back YouTube exist for all these operating systems; this is the subject of the several following slides.

As many users spend a lot of time watching YouTube (and other) Web videos, it’s definitely worth elaborating on the alternative technologies of playing them back.
First, let’s elaborate a bit on the two major formats YouTube content is delivered: the high-quality H.264 & FLV (with accordingly high data usage) returned by the firewall-friendly HTTP protocol, and the low-quality, low-(QQCIF) resolution 3GP (returned via the firewall-unfriendly RTSP protocol). We, of course, will mostly be interested in the high-quality version – unless we really need to decrease data usage and/or use a low-resolution mobile device like a MS Smartphone with a 176*220 screen.
The desktop YouTube Web interface isn’t the best for mobile usage (slow, huge – over 300 kbytes – pages; only Symbian + Flash Lite 3 is able to play back inline videos). There is a mobile version created and supported by YouTube, which
* Already supports all the functionalities of the desktop (account, upload etc)
* Is compatible with most mobile platforms having an RTSP / 3GP player like RealOne – no additional player needs to be installed
* Already has all the videos, unlike a year ago when it became public
However, it’s lower-quality 3GP only (no FLV / H.264) and requires RTSP. That is, it can be vastly inferior in most cases and, therefore, should be avoided.
The screenshot shows the results of a search using the native mobile YouTube interface (which, again, should be avoided, unless you absolutely don’t need the vastly enhanced video and audio quality of the FLV / H.264 videos).
Let’s continue with alternate YouTube technologies – ones that don’t depend on the Flash plug-in (because of the slow and flaky Flash plug-in on Windows Mobile) or are usable on other platforms like the BlackBerry. Fortunately, there are several of them; one of the most important is vTap.
vTap has native clients for all mobile platforms. From the Windows Mobile one (see the upper right screenshot), you can even initiate video playback (this client is highly recommended and useful because it’s capable of searching on not only YouTube but also other video sites), while you can’t do the same from the BlackBerry one.
This also means you’ll need to turn to other solutions to stream YouTube videos to your BlackBerry handheld; an example of these solutions is vTap’s Web interface (not the standalone client) depicted in the three screenshots at the bottom, showing searching for clips, opening them as a stream and, finally, the media player rendering it. (Note that the rendered contents is invisible in the screenshot on the bottom right. This isn’t a bug.)
Finally, one of the several alternative YouTube playback solutions is YTPocket, which depends on the external TCPMP FLV playback support (under Windows Mobile). The two screenshots show the results of a search and, then, initiating a download (and the consequent invocation of TCPMP for viewing).
Let’s move on to another, completely different, but, for users of non-unlimited data plans, very important question: reducing data usage. This, incidentally, can prove very helpful for users over unlimited, but very slow (for example, GPRS, like Vodafone’s non-3G dial-up) connections.
There are several ways of optimizations and major data usage saving; this slide discusses the way you can drastically lower the data usage by employing server-side (gzip) encoding, which is supported by all mobile browsers (for example, on WM, starting with the PPC2k PIE; that is, it has had support for eigth years).
As a rule of thumb, if you can, you should check the Accept-Encoding header (telling you whether the client is able to process gzip-compressed responses) along with the User-Agent HTTP header to find out whether it’s a mobile client (should you only want to return GZIP’ed contents for mobile users if you find GZIP compression is using too much CPU on your Web server). If you go this way, keep in mind that several mobile users “spoof” their User-Agent headers so that servers never return mobile-specific contents to them. With some of these clients (most importantly, IEM), you’ll want to look for specific extended (X-) HTTP headers to be able to make a distinction between desktop and mobile clients - that is, correctly identify mobile ones.
Note that several content manager and forum engines (e.g., vBulletin) support GZIP’ing “out of the box” if it identifies the client as a mobile device.

Unfortunately, if you are just a user and can’t ask a webmaster to return compressed (GZIP’ed) contents upon receiving requests from mobile clients but still want to (vastly) decrease your data usage, you’ll need to do some client-side work. There are two main categories of doing this.
The first group, largely consisting of the free Toonel and the commercial (between 30…50 US$ - cheaper for recurring customers) OnSpeed, runs a “proxy” on your Java-capable and/or Windows Mobile-based mobile device and configures (or, forces you to manually configure) your browser to access the Web through it. The proxy takes care of compression by being connected to another, invisible server. The advantage of this solution, compared to the next, is mainly that you 1. don’t need to pay attention to visiting a mediator Web page to do the conversion for you and 2. you will always receive full Web pages, not dumbed-down ones without, for example, scripting.
The second group consists of Web services like Skweezer, MobileLeap, Google Mobile etc. They are easier to initially set up than the apps in the first group (absolutely no need to install third-party apps on your mobile); however, they’re a bit harder to use and, as has already been pointed out, they can royally mess up Web pages. Most IEM plug-ins like MultiIE, PIEPlus and Webby automatically support the online services; the first two (Toonel / OnSpeed) can be used with all Windows Mobile Web browsers allowing for proxy usage (that is, everything except Opera Mini and TH – not a problem though as they’re content-stripped / compressed already).
Let’s turn to an entirely different subject: compliance with different (important) Web standards. Let’s start with AJAX, which is getting more and more ubiquitous. Opera Mobile and Minimo have the best support for it; the two screenshots show these (OM on the left, Minimo on the right) rendering the entirely AJAX-based Google Image.
Unfortunately, IEM is (still) pretty weak when it comes to AJAX support, even as of WM 6.1. So is NetFront as of the currently commercially available 3.3; fortunately, 3.4+ is already much better. (But, again, currently, there’re only restricted Technical Previews of 3.5 you may not want to use because of the restrictions). Thunderhawk and Opera Mini both have rather poor support.
JavaScript support is pretty similar to this. The bad JS support of IEM results in, for example, Yahoo Mail buttons’ not working – a major problem with many users. The same stands for for example address autocompletion in Google Mail; currently, only Opera Mobile and Minimo support it (they have the best JavaScript compliance).
Still on the subject of Web standards compliance, let’s take a look at the compatibility with CSS. In this area, Opera Mobile is without doubt the best as of version 9.xx. Version 8.65 (the one officially and commercially available; screenshot on the left) is a bit worse in this respect. Minimo is the second (screenshot on the right). The slide also shows how the desktop (9.x-series) Opera renders the test page (the only desktop browser to render it without any glitches – see the referenced article for more screenshots of other desktop browsers if interested).
Let’s go on with evaluating the CSS2 (Acid 2) test results. This slide shows how NetFront 3.3 and IEM render the test. As can clearly be seen, they (particularly IEM) have nothing to write home about.

Still on the subject of Web standards compliance, let’s see the results of W3C’s brand new “Web Compatibility Test for Mobile Browsers” suite. First, let’s see how the Windows Mobile-based Web browsers render this suite.
This slide shows IEM in WM6.1 (left), the 5-year-old WM2003 (middle) and 7-year-old PPC2002 (right). As can clearly be seen, the Web standards compliance of IEM is only a tad better than that of its very old PPC2002 ancestor.
Let’s continue with the same W3C test suite, looking at the Opera Mobile and Mini results. The left screenshot shows Opera Mobile 9.33, which delivers almost flawless results (showing it’s indeed based on the new, 9.x-series kernel), as opposed to version 8.65 (2nd shot). Opera Mini 4.1 (on the right) delivers acceptable results – still much better than, say, IEM (see previous slide).
Let’s take a look at the third (and last) Windows Mobile W3C test slide showing the current Techincal Preview of NetFront 3.5 (left); the WebKit-based Iris browser (middle) and Minimo 0.20 (right). As can clearly be seen, none of them really excel – Opera Mobile 9.x is just far better than any of them.
Now, having finished with Windows Mobile, take a look at other mobile platforms. In the lower row, you can see the WebKit-based Symbian Nokia S60 Web (left), iPhone’s Safari (middle). The built-in browser coming with BlackBerry 4.2 (right) follows; the latest (still beta), 4.5 BlackBerry version (topmost) shows the new BB operating system indeed delivers a bit better results than the previous one – but still much-much inferior to even Opera Mini (which, incidentally, runs flawlessly on the BlackBerry).

Finally, in order to give you a complete picture of what you can expect of desktop browsers, an overview of their rendering the same test. (On the bottom: Firefox 3 beta5 (left); Internet Explorer 8 beta (middle); IE7 (right); on the top: Opera 9.5.). As can clearly be seen, Opera is by far the best and even the latest version of IE8 is far-far inferior than even the latest 3-series Firefox.
Now, let’s discuss the techniques needed to avoid certain HTML / page layout constructs that simply can’t be rendered by (some) mobile Web browsers. The most important stumbling block is that of frames: both IFrames and standard ones. First, let’s take a look at the latter.
With IEM (as opposed to most other major browsers) the number of (standard, not i-) frames is restricted (10/12 at most for pre-WM6/WM6+, respectively). One of the most widely known example of the affected pages is freemail.hu. The pictures show IEM (on the left) was simply unable to display the page in its entirety, unlike Opera Mobile (right), which has no frame limitations. Make sure you avoid an excess number of frames if you want to make your portal accessible to even IEM clients and you don’t have a specific mobile version!
Now, let’s take a look at Inline Frames (IFrame). They are in no way supported by pre-WM6 IEM and Thunderhawk. The former is shown in the screenshot on the left, showing the pre-WM6 IEM’s inability to render the contents of the test page. NetFront and Opera Mobile, on the other hand, have no problems rendering this area (neither has Opera Mini).
The lack of IFrame support also means no Gmail / Yahoo Mail dynamic address completion (which works in Opera Mobile and Minimo) is possible because they’re entirely based on IFrames.
This slide shows IEM coming with WM6 has indeed added support for Iframes and has raised the number of standard displayable frames to 12.

This slide explains some common cookie handling-related problems with NetFront and Thunderhawk. The text speaks for itself; no need to explain it further (rather than following the links to my original, lengthy articles and elaboration).
The next few pages elaborate on the language & encoding problems and internationalization (on Windows Mobile), which will be pretty important for you if you display / host / try to access pages not (only) using non-Western languages – or, for that matter, even special punctuation like “.
First, NetFront handles the HTTP character encoding header (Content-Type) vs. meta tag entirely differently from the other browsers. It is, unfortunately, buggy when 8859-1 is used along with special 8859-1 punctuation – for example, if you write your posts in Word and don’t disable its automatic character substitution enabled (and active) by default.
Opera Mobile is pretty problematic at POSTing (NOT displaying /rendering!! Only when user interaction / form-based posting takes place) some contents; for example, special 8859-1 punctuation and everything different from 8859-1.
To easily fix these problems, if you’re a webmaster and know your pages do contain some special punctuation coming from, say, Word and want it to be rendered by NetFront or editable and (re)POSTable by Opera Mobile correctly, do convert dynamically (in the runtime) all these characters to their 8859-1, “plain” equivalents.
If an Opera Mobile client edits a non-8859-1 document (like an article or a forum post), convert all special Unicode characters (like ő and ű) to HTML char entity codes (ő and ű with ő and ű, respectively). These entity codes are correctly POSTed back by the browser.
As has already been mentioned, Thunderhawk uses its own, Western-only character set. It contains absolutely no other characters. Even when the operating system does support the given character set (and is able to render all the characters well), Thunderhawk won’t and just display a hyphen as a placeholder upon encountering them (the text in the screenshot shows some of these). Therefore, in order to correctly display non-Western, but easily 8859-1-mappable languages (typically, Eastern-European languages not using Cyrillic characters belong to this category), as a webmaster, you may want to check for ThunderHawk User-Agents and substitute the characters accordingly when encountering a TH client.
Some Web pages (and Web frameworks / content handlers) allow for easy internationalization – that is, dynamically returning a different-language page upon encountering a special HTTP request header. This slide elaborates on this and lists the two browsers (PIE and Minimo) that do let for setting this particular header. Unfortunately, the other browsers need an external HTTP request header rewriter proxy running anywhere (including your own PDA) to gain access to this functionality.
The two screenshots show IEM rendering b2evo’s login screen in English and Finnish (with automatical swithcing between them; no need for user interactions / language selection via links on the page), depending on the preferred language flag sent by the client.

Unfortunately, several mobile browsers don’t really shine at Web standards compliance either when it comes to downloading and saving binary files to the local file system on these handhelds.
The problems most users face:
* Content-Type: text/plain response problems with binary content: IEM & NF don’t try to decide whether the body is binary and blindly render it – as opposed to IE on desktop Windows. No such problems exist with other Windows Mobile browsers. That is, make sure Content-Type is correctly set on the server to allow for binary downloading to IEM & NF! Alternatively, if you are just a user and have no effect on the webmaster’s correctly setting this header, either use an IEM plug-in allowing for saving link targets, use a standalone HTTP downloader tool like Adisasta WinMobile Download Accelerator 2+ or HandyGet - or switch entirely to a different browser.
* NF and Opera Mobile send out download requests twice, while other browsers – including desktop ones – only do this once. This is why for example downloading from RapidShare doesn’t work in these browsers. If you’re a webmaster, the solution is simple: never reject double download requests. If you’re a mobile client only, switch to IEM – at least for the time of download.
* Referer-related problems: before WM5, PIE (and Thunderhawk even now) don’t pass the Referer header. Therefore, if you’re a webamin, don’t blindly trust the Referer header always being sent in order to deny out-site download requests. Just make a User-Agent test to check whether download requests not containing a Referer header originate from PIE and TH. If they do, you can safely let them download.
Note that you can greatly speed up your Web (and FTP) downloads by using multithreaded downloader clients (like FlashGet on desktop). Currently, two of them are worth mentioning:
* The just-released Adisasta WinMobile Download Accelerator 2.0 (do NOT use older versions because they’re slow!)
* HandyGet 1.6
The final slide discusses the opposite of the previous one: uploading files to Web. File upload is supported by all browsers (except for TH); IEM starting with WM5. As Opera Mini 4.1+ also supports it, you can even upload from the otherwise not very capable BlackBerry platform.
If you have a browser that isn’t upload-capable, then, switch to another browser that can. And, if you’re a webmaster hosting a page with file upload capabilities (like all forum engines, social network pages etc. allowing for attachment / image upload), you will need to ask your mobile clients to do the same. Alternatively, if you’re absolutely sure some of your clients won’t want to touch other browsers, you may also want to provide FTP upload support or, if you only look for text input, a HTML textarea to paste their text to.
The left screenshot shows PIE under WM2003SE. As can clearly be seen, there’s no “Browse” button (and file path field) in it – while the WM5+ screenshot (on the right) already displays (and lets for using) it, showing it (still) didn't have upload support.
That's all, folks - hope you liked this all And, yes, feel free to ask questions even here, even now.
