Is the HTC Touch Pro able to work on U.S 3G band , if not is there a radio patch that will activate the U.S band on the device. Please help.
This is a very hot topic on this forum but so far from what i've been able to see none of the radios have enabled 3G. This is not to say that 3G isn't supported by the hardware although its looking pretty grim. It appears that the ELITE team is working on this since they just released Hardspl

We shall see what happens, although the bands are available in the "band" settings tab so it MAY be a radio issue.
Bit early to know yet, as there is only one user here so far who has hold of an AT&T Fuze (RAPH11000) we dont have a huge ammount of detail yet.
Both the newer 1.02.25.31 and 1.02.25.19 radios seem to have similar protocols (same QCT_BOOT and HTC_BOOT), it would be good if any user could flash the (apparently) older 1.02.25.11 radio and see if it does anything?
I really wish i could help out on this 3G front but no 3G in my area...
I can help...

I have the 1.02.25.19 radio here in Chicago. I know I have good 3G coverage from my TyTN II that I had previously. But why would you think the OLDER radio (1.02.25.11) would have U.S. 3G? ...jus curious.

I've installed the radio 1.02.25.11 and no luck with 3G in US ATT. only edge support.

I tried all the radios listed on the wiki too. None of them worked with 3G.

Its bundled with the AT&T ROM which is currently on the AT&T Fuze devices people are testing.
Higher radio version number doesnt necessarily mean a better one, as veterans of the Hermes will verify
The overseas Touch Pro cannot get 3G in the US. Just like the Diamond, the Touch Pro from overseas (RAPH100) does not have a WCDMA 850 radio.
Flash all the radios you guys want... it's not going to get you 3G on the 850 band. You'll have to wait for the US version/ATT Fuze if you're in the US and want 3G data.
Anyone know when AT&T sould release US version/ATT Fuze?

Until we have tested newer ROMs and radios that statement is pure speculation. MANY devices have had missing bands and etc...but have had them unlocked in ROM and Radio updates so it is too early to be writing off 3G support yet.
I have a TouchPro coming tomorrow. I called HTC today and (although I have about as much confidence in this as the paper I wrote this on) I was told by a lower level tech (I think he knew what I was talking about) that a "software" upgrade would allow for the European 3G enabled device to work in the US for 3G
... I sure hope so since I forked out the cash today
The Treo 750 didn't even start out 3G capable at all and was made 3G able with a ROM upgrade
Hoping
Hardware
Maybe a very stupid question, but what about openning up an eu version to see if the quad radio hardware is there? I would assume the radio chipset would be labeled and numbered so that we would know once and for all.

I thought about this but cracking open a 900 dollar device and completely voiding the warranty really isn't worth it. If someone can get schematic from HTC which i doubt we could see if the hardware is installed.

I believe there is an asian hardware version, this is what the HTC techs keep mentioning that might have the 850 3G radio.
I have a case into HTC support asking them to answer the question for me around if the radio is hardware capable of 3G in the US and explained what bands I was talking about and that it was in the software to enable those. I Posed the question as if I was unhappy that I was selecting these bands and it wasnt working to try to get an answer out of them will report back when I am answered one way or another.

Just so you know - I sent a similar email to them regarding the 850 band on the Diamond and I was sent a very nice response informing me that the phone I purchased was not intended for the US and did not have the hardware capability to be used on ATT in the US. Low and behold the xda developers made the 850 band work. Now HTC offers a rom upgrade opening the 850 band they said was not in phone. Unfortunately the response you get will not be the definitive answer.

I understand yours and others' reasons for not believing me or assuming it's speculation. All I can say is there will be a lot of effort put forth for no reason, just like with the DIAM100, only to confim that the hardware everyone is trying to unlock isn't even there. If the efforts put forth do nothing more than prove the above to be true, then at the very least people can rest more easily with full confirmation.
Hi,
I was just wondering, I was told that the G2X is a dual band phone, to me that means that it will work on T-mobile's network and At&t's as well for incase the merger happens. If this is true then is this the only one of it's kind that T-mobile has to offer? I want to get 1 last T-mobile phone before the merger happens. I know word it it could be a few years before any changes that effect us T-mobile customers and our Devices but you never know. So I thought if I was going to spend some serious coin on a new phone it may be safer to get one that works with both.. or should I not even worry about that at all right now? Any opinions or inside scoops? I'm not to up on this.
Thanks,
Kn0t
As far as i know it's dual band yes.
No, as far as I know the phone does not support AT&T's 3G bands (850/1900).
I think the only phone that actually supports both T-Mobile 3G and AT&T 3G is the Nokia N8. The Samsung Vibrant partially supports AT&T 3G, but only on the 1900 band, which means you'll run into issues in 850 areas and probably drop to EDGE in buildings, etc. where AT&T relies on 850 for better penetration.
Having said all that, the G2x is certainly a good phone. I would recommend it over a Vibrant (and definitely over a Nokia N8). The AT&T merger may not even necessarily happen (it is not 100% confirmed yet). I would not worry about that right now, unless you intend to actually stick with the same phone for at least 1-2 years. I know for me personally that would be hard to do (except for some devices).
I have the g2x...it's a great phone...and it's been confirmed NOT to support AT&T's high speed bands. Still, well worth recommending, but if/when the merger goes through you'll need a new phone. My contract just came up and I popped for it. AT&T supposedly will offer us "comparable" devices when the time comes.
Hope this helps...
So there is millions of AT&T crap network without 3G service across the US. Does anyone feel like I do in the sense that AT&T is doing this as a stunt to the government to show how crappy their network is and why they need to dismantle the beautiful creation TMO created with HSPA+. Its sad the AT&T has to stoop so low to get what they want.
No because each run off of different 3g technologies ...plus at&t is going lte for their 4g

i disagree both AT&T are both GSM the only difference is the frequency they operate on. AT&T will dismantle TMO HSPA+ for their "LTE" rollout. of course raise prices.
AT&T didn't storm Deutsche Telekom's offices with guns to get them to agree to sell T-Mobile U.S. Deutsche Telekom is in a world of financial hurt and needs the $39B to reinvest in what's left once T-Mobile's gone. In fact, they're giving back 1/3 of the $39B to shareholders after closing to compensate for their ****ty financial performance.
T-Mobile U.S. has the lowest yield per pre-paid customer of all four carriers, the highest attrition rate, the highest bad debt write-off, and the lowest margins. That all adds up to less money to invest in new products and services in a highly competitive environment. None of this is sustainable for a public company that answers to shareholders. So if it wasn't AT&T, it would be Sprint or private equity (which means slash and burn). Fat, dumb, and happy wasn't ever really an option.
Let your voice be heard. Go to the FCC website, and post your comment about the merger. fjallfoss dot fcc dot gov/ecfs/hotdocket/list proceeding number 11-65.
@flack0, they have different radios, hence the reason a T-Mobile phone will not run at&TS 3g and an at&t phone won't run tmobiles 3g

Unless you have a G2x with unlocked AT&T frequencies or the other high end phones that Tmobile is coming out with that supports both Tmobile and AT&T 3G frequencies.
Tmobile is pretty confident that the merger is going to go through and is releasing some of their high end phones with dual support
Those rumors about the g2x having both at&t and T-Mobile 3g/4g bands have been long proven to be false...same with the sensation ....to my knowledge there isn't a phone out as of yet that supports both. Please correct me if I'm wrong ...and if you unlock this phone to at&t it will work, but only on edge and wifi

ATT gave half a billion dollars to democrat lawmakers to ensure the deal will go through. It's a done deal. Tmobile is history. All hail new higher prices and crappy service.
I plan on re-signing a new two year agreement at my grandfathered pricing as late as possible to push back the inevitable price hikes.
Edit. The dems recived $500,000 in contributions from ATT. Sorry for the typo.

??? Not that I doubt you, but do you have any solid proof that it will work on ATT 3g? Conformation from ATT, Tmo or LG? Have any of the companies involved guaranteed it will work? All that thread says it should support it. I find the claims that it is locked down and hidden but will magically work later dubious at best.

There are several phones out right now that support 3g on att and tmobile nokia makes atleast 6 phones that are pentaband wcdma 5 bands and the tmobile vibrant will do 3g on att Band I (UMTS 2100, Europe's main 3G band)
Band II (UMTS 1900, US band)
Band IV (UMTS 1700/2100, US band)
Band V (UMTS 850, US band)
Band VIII (UMTS 900, Europe and used e.g. in France and Finland in rural areas)
Well you saying it ISN'T possible isn't warranted either.
The hardware specs specifically say it supports those bands. Tmobile also said it supported those bands. LG said it supported those bands. It passed the FCC with those bands.
Tmobile stated that several of their high end phones will support the AT&T 3G bands and will be unlocked to do so once the merger goes through.
The G2x was the first to support them. The Sensation doesn't. I think the Hercules will as well (although be still be locked until the merger).
Now really, no one REALLY knows one way or another... but looking at the evidence (which are referenced all over the place) it would be best to say that one day we COULD have support for AT&T 3G (unlike the Sensation which doesn't have the hardware).
We do have the hardware but it is locked down. Being it is such a new phone and we don't have any other baselands available, we can't simply flash and be successful. Perhaps the Canadian version will have them all unlocked and we can use theirs.
But to say it isn't possible is not proven just as much as saying it is possible. I would say it IS possible but not right now (AKA it doesn't work out of the box).
i hope you're right sir....that is if the merger happens

The hardware specs are all over the place. It was only AFTER the phone was released that Tmobile said the phone didn't support it and it was restricted by "hardware".
pfft.
The G2x is based off the O2x. Sure slightly different but I would almost bet they used the same "quadband EDGE, and quadband HSPA+ (with future-proof support for 2100, 1900, 1700 / AWS, and 850MHz)" chip.
I bet the G2x and the O2x use the same chip. Tmobile probably just ordered it to be locked down (lack of drivers or something).
It would require a tear down of both the G2x and O2x to be certain.

"all over the place" ... "I bet" ... and "probably" don't really prove anything. You're just speculating, and so far it's based only on your opinion because you haven't provided any sort of links or references to prove your point. The only things I can find regarding the G2X having quad band HSPA+ are when T-Mobile admitted that they were wrong in saying it supported those bands in the first place. On LG's own website they list the G2X as supporting only 2 HSPA+ frequencies (1700/2100). Also on LG's website, they list the O2x as supporting 3 HSPA+ frequencies (900/1900/2100).
It would be awesome if T-Mobile had been correct, but there is nothing I can find that suggests they were. I'm just asking that you pull one or two links from your "all over the place" evidence so that I can have the same faith that you do. I'm not finding it, so I'm asking you to show me. That's all.
Here are the links to LG's product listings for the O2x and the G2X, and the specifications can be viewed by clicking on the specifications tab for each product:
G2X here: http://www.lg.com/us/mobile-phones/LG-P999.jsp
O2x here: http://www.lg.com/uk/mobile-phones/all-lg-phones/LG-android-mobile-phone-P990.jsp
**EDIT** -- Let me just add that I sincerely hope you prove me wrong, because that would be some awesome news about this phone.
I was under the impression that LTE would not be supported until Tango or Apollo, but the AT&T Titan II and Lumia 900 will have LTE while running Mango.
Is it something special about AT&T's LTE network that allows this? Or did Mango always support LTE?
If Mango supports LTE, how far off does an LTE WP7.5 device for Verizon seem? (Verizon said that the reason they don't support WP7 is due to lack of 4G LTE)
I'm not sure if 7720 supported LTE, but I think one of the newer releases does.
Mind you, LTE or not, AT&T uses GSM and Verizon uses CDMA, and it may just be that, while both are supported independently, the combination of CDMA with LTE is not yet tested. After all, most of the world uses GSM; CDMA wasn't supported at all until 7389 (NoDo).

Does it matter whether the phone uses GSM or CDMA for 2G/3G? LTE is a GSM technology (hence the LTE SIM cards on 4G Verizon phones), so I figured it'd be all the same to the phone.
I'd guess it's the combination of the technologies, since the phones aren't pure LTE. Being able to fall back from LTE to 3G CDMA, or being able to do data on LTE while taking a call on CDMA (something pure CDMA phones can't do at all), probably requires a bunch of extra work and testing.
It's also worth noting that Verizon may just be misleading people. They've shown no particular interest in the Windows Phone brand at all, right from the beginning. Between "Droid"-branded Android devices and iPhones, they don't seen too interested in other platforms.
I want to say yes it does because T-Mobile has 4G Windows phones at their stores.
T-Mobile isn't using LTE yet, though. Their "4G" is really more a "3.5G" technology - it's a faster variant of their 3G, not a completely new tech. It let them bring it to market early and deploy it widely, and it *is* pretty fast, but it's not LTE.

I stand corrected.
Mmkay. So my understanding is that Mango supports LTE on a GSM network (AT&T) as of now, but not LTE mixed with CDMA (Verizon)?

I guess I have to say on Verizon's defence, They only had a choice of 2 devices, because of their CDMA network. It's Microsoft that limited the options for Sprint and Verizon.
Yes, I do also believe that Verizon has Android and the iPhoney so far up their ass they don't see anything else...BUT, they have released in a Press statement that they would be interested in WP7 if it had LTE options available. Maybe the Lumina 900 would come to verizon...
Maybe we will, maybe we wont...
Waaaait... *Microsoft* limited the devices available to Sprint and Verizon?!? Not Sprint and Verizon themselves, who chose to use a technology almost nobody else in the world uses. Not the OEMs, who didn't build more CDMA-based WP7 devices. No, it was Microsoft, who will license WP7 to anybody who wants it and who have both a CDMA and a GSM version, who are to blame here? I'm confused.
The OEMs are the ones who decide what devices to manufacture. Of course, they do that based on having customers. If Sprint and/or Verizon were to ask for more WP7 devices, you can be sure HTC, LG, Samsung, Nokia, and maybe even Dell, Asus, or Sony Ericson would be willing to provide (Motorola seems to have no interest). Heck, Toshiba/Fujitsu *has* a CDMA/GSM hybrid phone running Mango - it was the first gen2 phone ever released! I'm actually surprised Sprint *hasn't* started importing it; the IS12T is a nice piece of hardware, and would complement the Arrive well.

It's not Sprint and Verizon's fault for choosing CDMA over GSM. They made the decision years ago, before smartphones even existed.
CDMA is actually the smart choice for a big country like the US. Each CDMA radio tower has a larger cover radius than GSM radio towers. Not only that, the call quality is usually better.
And China predominantly uses CDMA. As time passes, CDMA will become more prevalent.
That said, it's not Microsoft's fault, either. The reason there aren't many CDMA WP7 devices is due to OEMs not making many of them.

Keep in mind, the world is about 90-95% GSM. Microsoft decided to support the world wide standard before they went to CDMA on release(it was publicly stated by Microsoft). So, yes, it is sort of Microsoft's fault why there is only 2 US CDMA models.
OEMs knew this too. Make phones for 90-95% of the world or promote your efforts to a smaller market. It makes total business sense why it was done this way. Windows Phone 7 Didn't even support CDMA till NoDO months later after release.
China's CDMA is not the same as the US CDMA, its almost totaly different, WCDMA, they dont work together, so it's a different chipsets needed.
WIth that being said, Verizon or Sprint could of dumpped money at the project to get more WP7 devices but, with the problems with WM, they held back a little.
So, it's Microsoft and the carriers fault for the lack of CDMA phones. LTE is another thing totaly. We should hear about LTE WP7 phones at WMC coming up very soon.
A release for LTE based CDMA phones is another story....

CDMA is actually the smart choice for a big country like the US. Each CDMA radio tower has a larger cover radius than GSM radio towers. Not only that, the call quality is usually better.
And China predominantly uses CDMA. As time passes, CDMA will become more prevalent.

OK, this is something I will address. There are three large mobile operators in China: China Mobile, China Unicom, and China Telecom.
China Mobile uses GSM/EDGE for 2G and TD-SCDMA for 3G.
China Unicom uses GSM/EDGE for 2G and UMTS for 3G
China Telecon uses CDMA2000 for 2G and EVDO for 3G.
What the local Chinese refer to as "CDMA" is actually W-CDMA which is a UMTS technology.

If Mango supports LTE, how far off does an LTE WP7.5 device for Verizon seem? (Verizon said that the reason they don't support WP7 is due to lack of 4G LTE)

Whether or not Verizon choose to carry LTE Windows Phone is a political issue, not a technical one. Windows Phone does support both LTE and CDMA2000/EVDO.
so im trying to find a non-smartphone that works on att. i was just going to stick with att phones but i see alot of verizon phones that i like. i understand that an at&t phone needs to be compatible with umts 850-1900 for 3g specifications since att shut down 2g but what about tmobile/verizon specs? i see alot of verizon phones with cdma 800/1900. would that mean it would work withh att after unlock?

I wouldn't bother with a 3G device, many networks are dropping or will be dropping 3G in the very near future, it would be a waste of time, money and headaches to go for a device that is quickly coming to the point of no longer being supported.
