Positioning Through GSM/GPRS - General Topics

Hey all,
A question here, i have heard this story a couple of times now but no proof. So maybe one of you can tell me if its a hoax or not.
I heard about a program that is able to triangulate your position by checking the signalstrenght. The program i heard about would be able to change to profiles to whatever you set them and whenever they should be activated.
For example: you come home, the program finds out you are close to home and puts on another callprofile etc.
The fact is that i know of LBS (location based service) and that those services are also working on the triangulation of cellphones.
Basically it should be possible but i can't find anything about a single program that is able to do something even close to that.
Do some of you have some more information if there is such a program or if its even possible?
Thanks!

I have been looking for that for years. It's the replacement of GPS (carry one more device). However, I search through the webs (visisted more than 100 sites). Some were restricted (police use) and some were requiring service charges per Kb.

Search for "navizon". I remember reading about it on here somewhere - let me know if its what your after and if its any good please.

Specs off navizon are very promising. It claims to use all available cell, wifi & gps data on p2p basis to locate your current position. Unfortunately PIE & Minimo aren't capable of downloading the installl files, so my try-out is a bit delayed.

Thanks for the info petest. That looks very promising indeed!
It even has the possibility to let GPS software use it.
I just installed the whole package and fired it up but still no positioning data after 20 minutes.
I'll let it run for a day and see if something happens.
But thanks for the info and i'll let you all know if it starts working!

CoPilot trial and internet connection

I've searched in the forum but I didn't find anything about it.
I've just installed the trial version of CoPilot for TD2, but every time I launch it I see a message that sounds like "CoPilot needs to confirm your trial period by accessing Internet every time you use it".
So the question is: does it really connect to internet every time I start the program? I'm going abroad and I was planning to test it, but if it is going to use internet it will cost me a fortune!
Thank you
Bruno.
I used the trial and as far as I can tell it does try to check each time its run, try an experiment, block your data connections (NODATA) then see if it runs, I did have a situation where I didn't have a data connection (bad signal area) and it did start up, it might not need to check every time??
I did have some issues with Copilot though, if I went find a destination from a Contact section, as soon as I selected a key on the keyboard (to go to a contact) it crashed out. Also it had trouble with several contacts in finding a street location for them.

I had a big arguement with CoPilot support about this - the software does in fact require internet connection to verify your status everytime you start it - I pointed out to the guy at CoPilot that this was ridiculous since on their start page they say that "Copilot doesn't use mobile internet for sat nav" .... but you do need it everytime you start it so without internet connection, you can't really use Copilot even though it might not need it for the satnav part!!!!
But, whilst trying it out, I think (but no guarantees) that once you log on to start Copilot, it might place some kind of tag about the expiry date and if you then block your data connection, you may still be able to use it by clicking on cancel on the welcome page of Copilot that tells you it needs to verify your license.
So give that a try and see if it works .... good luck and happy travels
Not a problem for me
Hi all
I used Copilot during the trial period and since buying it and it's never asked for an internet connection when the wireless is off. It's version:
7.8.0.351
Cheers
andrew-in-woking
What map version do you have? In trial it's only 0804.
0804 maps
Hi
Yep, 0804 maps. You don't get anything extra when you buy it.

trace/track a GSM mobile telephones location

Hi All,
I know it is possibile to trace/track a GSM mobile telephones location all over the world.
I also know some compaines does this for chargeable service.
I am VERY interested in getting this for free! (I bet you are also).
Anyone know how to do this without empty our pockets??
Thanks,
in fact, i have the same interest.
who wouldnt love to know how to do this?
The only information you can get out of your own phone, is the ID of the basestation it is attached to. This is held in a register in the phone internals that can be read via the RIL interface.
It is also stored in the SIM. If the phone is totally powered off it will attempt to connect to the last known good base station on power on. (Quicker than sniffing around all available frequences for an suitable station.)
While a change of basestation could be detected by software running on a phone, only the Telco's database has the location of all active phones, so they can inform the basestation to contact your phone if there is an incoming call or data.
This data is theirs and theirs alone. It is valuable and confidential, hence the charge for any use of it.
In short all you can find out from your phone is where it is. But you know that anyway.
Erm... I just wrote this and then I realized that you want to track the device via GSM and not GPS. This will only work with GPS (can be activated in the background), sorry.
Just look for an application that allows you to track your device if its stolen. Some of the programs still work after changing simcard (which is not really interesting if it did not get stolen in the first place...). If everything is set up, you can easily receive a sms with the current location (you need to activate the programm by sending a sms).
If you need to know the exact position of the device like every second, you can use a jogging-trainer which logs the speed etc. But this will only store the positions on the device (you can upload them to your computer, but this can probably not be done via any wireless connection.
My english is not the best, I am sorry. But I am sure you're gonna understand everything ;D And no, I don't know any programs name because I don't use them.
XphX
Stephj, are You talking about GSM or CDMA? Because for GSM I know for sure that the Telco knows a bit more - at least it is possible to triangulate the user's approximate position using three or more base stations (and probably user's signal strength for each base station too). So the DB should hold more info about the base stations available to user's current position, as for example "ready to go base stations" or something like that.
For tracking the phone, you can try GLympse or LookOut, Look out is better if you loos your phone, it synchronize with their website, and can see the location on the phone anywhere in the world, even can delete your data from your web account on look out.

GPS Settings: Performance Options (improvement)

Ok, There are a lot of posts and information regarding the GPS issue that some are experiencing. I am starting (yet) another post in the interest of compiling and maintaining information regarding that information in one location. As users/devs find out information I will update this post so everyone doesn't have to go looking everywhere for the information. I am hoping that the Moderator will sticky this post.
Some users are experiencing very long lock times for their GPS. Everyone, after reading A LOT of posts/threads it seems to be the consensus that this is a software/settings issue - NOT, a hardware issue. However, results from tweaking the following settings are very mixed. Most seem to get great results by tweaking the following settings while stationary - but, moving is a whole different ball game. I use the below settings and have great results while stationary. However, my G1 blows the Captivate completely out of the water!!! My G1 gave 3-10m accuracy while driving. This device can barely keep me on the correct highway and always seem lagging behind my current location. The G1 was spot on no matter what. What hasn't been determined is if these issues are hardware or software. For whatever my opinion is worth - I think it is a firmware/software issue. Here are some things to try.
Here is the info:
To get to your GPS settings open you dialer and dial the following number. This will not call anyone - it is a code shortcut to the settings:
*#*#1472365#*#*
Once entered you will observe a screen that has five buttons:
Get Position Test
Application Settings
SUPL/CP Settings
Test Application
Delete GPS Data
We will be interested in three of these initial buttons.
Get Position Test: This will be what one uses to test the results of your changes.
Application Settings: Exactly what it says.
SUPL/CP Settings: settings that determine specific data connectivity with the satellites.
In Application Settings the following are some that you might consider adjusting:
Operation Mode - Standalone, MS Based, MS assisted, Network Provider
Accuracy - defaults to 50. Don't set it below 10 (and only use increments of 10's)
SkyHook - not sure what it does. But, someone on a thread mentioned it and it DOES effect satellite lock times.
In SUPL/CP Settings one we'll be interested in the following:
Server FQDN Type
Server
Server Port
The following are the options provided on other threads:
Original/Stock Settings:
SUPL/CP Settings/SErver FQDN Type/Custom Config
Application settings/Operation Mode/Standalone
SUPL/CP Settings/Server/www.spirent-lcs.com
SUPL/CP Settings/Port/7275
Second suggested setup (from other posts and claimed to have great results):
SUPL/CP Settings/SErver FQDN Type/Custom Config
Application settings/Operation Mode/MS Based
SUPL/CP Settings/Server/supl.google.com
SUPL/CP Settings/Port/7276
Other settings that I have played with:
Application settings/SkyHook/On (and Off)
SUPL/CP Settings/SErver FQDN Type/Auto Config (and Custom Config)
You can play around with these to see what gives you the best results. If your GPS doesn't work better with whatever changes you made - than you can always put it back to the orginal settings above.
However, it has been recommended and I concur (for whatever that is worth) that you NEED TO SET THE FOLLOWING BEFORE YOU START PLAYING AROUND: Settings/Location and security/uncheck (turn off) "Use Wireless Networks). Most likely this won't really effect anything while your testing within the GPS settings - however, this will effect your results if you test using Google Maps, etc.
Now, having duly noted all of the above and having played around with the settings for several hours I found the best results FOR MY DEVICE IN MY AREA AT ONE LOCATION was the following:
Note: I adjusted these settings from earlier as the earlier settings proved to be very accurate when stationary - but, very inaccurate while moving. The latest settings I'm using are below. Also, look to the bottom of this post regarding changing your gps configuration file. That also helped A LOT. The bottom section of information is from the Official websites that run the time servers(effects GPS performance).
Application Settings/Operation Mode/MS Based
Application Settings/Operation Mode/SkyHook/ON (VERY IMPORTANT)
SUPL/CP Settings/Server FQDN Type/Custom Config
SUPL/CP Settings/Server/supl.google.com
SUPL/CP Settings/Server Port/7276
SUPL/CP Settings/SUPL Secure Socket/Off
Turning "SkyHook" ON assisted in faster locks with ALL of my tested settings when stationary!
My test results with the above would lock on up to three satellites in under four seconds and between 7 and 10 by eight seconds. Google Maps would locate me in about 6-8 seconds.
Using "Get Position Test" the settings in the three lines above consistently gave the not only the fastest locks and the most locks - but, also STRONGER SIGNALS!
I used at least seven different combinations of the above settings and some of them were just as quick - but, not as strong. Most of them were slower.
If anyone has better information to add then please PM me and I will add it to this top post.
LASTLY, I will make some guesses as to what some of the other settings do as I have heard different information:
Application Settings:
Session Type: Tracking or Singleshot - obvious (use Tracking)
Start Mode: Hot or Cold Start - someone posted on a thread that Hot uses data from your last read to get started. Cold start will start all over. So, Cold start SHOULD increase the time for you to get a lock unless you went left the area to an area that had different satellite to look up.
Test Application:
Performance Test: worked for me - but, I found the test above to work faster and give me quicker results for what I wanted.
Hardware Test/Sensitivity Test: Pretty cool - went on forever and I stopped it.
CNO Test: Seemed to test the average satellite signal strength.
Antenna Test: Never worked for me and I received errors.
H/W Test Settings: Settings for the above tests - I didn't mess with them.
NOTE: WANT TO SEE HOW ACCURATE YOUR ACCELEROMETER/COMPASS/ORIENTATION settings are? Check this out:
Test Application/Show Sensor Data - there is no way to calibrate it here... But, you can see just how sensitive your instruments are!!
Delete GPS Data - I didn't select this button and I don't recommend anyone else doing so either unless someone from Samsung tells us what it does. LOL!
FINALLY: Keep in mind that if you are seeing GPS lock times that are in the 3-8 second range (which was what I was getting) this WILL NOT be how long it takes for Google Maps to get the GPS data! Expect 8-15 seconds or a little longer (but, under 30 seconds) for Google Maps to pick up your location. Although the GPS sensors might pick up the satellites - you still have to give the software time to evaluate the data and apply it to the software.
Hope this helps someone out there.
Update/Additional Information (http://androidforums.com/1194187-post197.html):
Hot Start - The GPS receiver remembers its last calculated position and which satellites were in view, the almanac used, and the UTC Time. It then performs a reset and attempts to acquire satellites and calculate a new position based upon the previous information. This is the quickest re-acquisition of a GPS lock.
Cold Start - The GPS receiver dumps all information and resets. It then attempts to locate satellites and then calculate a GPS lock. This takes the longest because there is no known information. The GPS receiver has to attempt to lock a satellite signal from all of the satellites, basically like polling, which takes a lot longer than knowing which satellites to look for. This re-acquisition of a GPS lock takes the longest.
Thanks to Shadow77895 for the link to this info. I altered the settings above. Doesn't effect my results much at all.
MSBased Operation Mode(http://www.vzwdevelopers.com/aims/public/menu/lbs/LBSFAQ.jsp#GenQues11):
What is MS-Based mode of operation?
In MS-Based mode, the network provides the satellite information to the device, based on a rough estimate of where the device is located, and the device acquires the GPS signals from the satellites and calculates its location. After the initial fix, the device operates like an autonomous GPS receiver, until the satellite information must be refreshed, at which time the device goes back to the network to update the satellite information. MS-Based mode is appropriate for applications that require the device location to be updated rapidly, such as a navigation application.

ALSO! Check out this page: http://www.pool.ntp.org/en/use.html:
As pool.ntp.org will assign you timeservers from all over the world, time quality will not be ideal. You get a bit better result if you use the continental zones (For example europe, north-america, oceania or asia.pool.ntp.org), and even better time if you use the country zone (like ch.pool.ntp.org in Switzerland) - for all these zones, you can again use the 0, 1 or 2 prefixes, like 0.ch.pool.ntp.org. Note, however, that the country zone might not exist for your country, or might contain only one or two timeservers. If you know timeservers that are really close to you (measured by network distance, with traceroute or ping), time probably will be even better.

REQUEST FOR ADDITIONAL INFORMATION:
Many are suggesting that we do NOT leave the Secure Socket ON. How will this effect data security with our devices? I don't understand how it could hurt us... But, there must be a reason for it. If someone could let me know I would appreciate it.
Good, guide, think you meant hot start should be faster though.
I'll be linking to this.

Great, but doesn't address the problem
I need to point out that while this information is helpful it doesn't really address the problem that the GPS is facing.
What the above settings are doing is enabling multiple different A-GPS technologies to help compensate for the Galaxy S's poor GPS performance. A properly functioning GPS unit would not need these crutches except to acquire a faster fix.
I had my GPS outdoors today, with the first set of recommended settings, and was unable to achieve a fix while seven satellites were in view (according to it) with sufficient signal strength. This is a GPS firmware issue!
The above post is very helpful for people to get some better performance - however - the core GPS issues need to be addressed by Samsung.
I hope people will refrain from saying "It's perfect now!" and let up on Samsung. Unless you know what what the following are you're tweaking settings blindly and declaring victory: ephemeris, PDOP, SBAS, WGS-84, 2D fix, 3D fix (And the conditions one is chosen over the other.) and finally SA
I'm betting this phone would never achieve a fix in an SA environment! It's also clear that the person(s) who originated this information knew exactly what they were doing..!
If anyone is interested in learning how GPS works there are tons of great resources on the web that Google will point you to. Of course they're written for all sorts of different levels.
In short, the above settings may help, but please don't become convinced that things are "fixed"!
I'd suggest you read my posts on the subject:

@haydonxda - I agree that this does NOT address the potential problem that the firmware and/or hardware is inadequate! And, we should put pressure on Samsung to fix this issue. However, the phones have already been produced and I'm just trying to do the best with I have.
@Shadow77895 - thanks for the info. Added a bunch of further information after looking into your posts and references from them.
Try this fix (from 4pda.ru), working on Galaxy S, root access required:
$su
#cat /data/gps/secgps.conf > /sdcard/secgps.conf
#rm /data/gps/secgps.conf
#reboot
After reboot, new (correct) secgps.conf appears.

How do you use the text editor in Root Explorer. I can see the text but it won't allow me to edit it.
Hello, the code:
*#*#1472365#*#*
starts a GPS Test Application.
The settings inside this application are only for this application.
You can test your GPS in different modes.
But the settings are not relevant for other applications.
It is a simple illusion that it helps to manipulate this settings.
GPS is very time-dependent.
And:
I don't know where we can change the default GPS Mode/s...
So when I walk outside my office there are like 7 satellites, and I still cannot get a lock. This is sad.
Out of the box it worked great, navigated from BB to my house with relative ease. Inside my house when I showed my parents it worked great. I rooted and deleted some ATT apps. I have yet to get a lock.
I have also changed the NTP servers and no dice. This is pretty saddening performance.
I still don't get why my Nexus One, sitting right next to my Samsung Captivate, is able to get a aGPS location (via My Location in maps) that is pretty damn accurate despite not having a GPS lock and my Captivate is unable to even get an aGPS location and just says my location data is temporarily unavailable.
Nexus One: Can get approximate location very easily
Samsung Captivate: Cannot even get approximate location using WIFI/Cell Towers.
Foursquare never knows where I am until I go outside in the middle of a parking lot. This is BS.
Won't anyone try GPS NMEA MONITOR App and see if the data sentences are correct? If the GPS chipset is putting out the correct Lat/Lon, then you can fiddle and fiddle what Captivate does with the information
Has anyone tried to contact Samsung about the issue yet? I tried yesterday and was on hold for an hour and half and then my call dropped. I'm joint to try again today.
SkyHook isn't a "feature" persay, it's a corporation: http://www.skyhookwireless.com/
Same one Apple uses. Not sure exactly how it works but they do wardrive and use WiFi and triangulation to pick up your position as well, so leaving that OFF will perhaps be better for calibrating your GPS settings, but you certainly want it back ON when in normal use.

What kind of aGPS does the Nexus One use? I tried to dial the code and it didn't bring up the same menu on the Nexus (it may be different). My Nexus is great at figuring out where I am without a GPS signal.
I changed all my settings last night and it seemed to fix the issue. I was getting a lock within 10 seconds or less. Now I cannot get a lock with the exact same settings and reboot. Has anyone contacted Samsung over this? Anyone get an answer from them? I love this phone but the GPS issue sucks.
Every time I try one of these new fixes it seems to work but then when I go somewher else it is broken again they need to fix this asap. I use that feature a lot

Don't give up hope, i'm sure that guy doesnt know anything. Engadget and a few sites are aware of the issue and i'm sure Samsung took notice. i'm sure a firmware fix is in the works.
Location
I have tried all the settings. And I don't really notice any difference. I live in the heart of Manhattan, NY., so I am sure roaming around int he concrete jungle trying to get a lock surely has a lot to do with my GPS issue. I do however, get a lock in every setting that has been written up in this forum, and other forums. The difference to me is hardly any, since it always takes many minutes for me to get a lock. I never have used any other GPS device since living here in the city, so I would like to ask other who live in a large city if it is taking them several minutes as well? Because it seems as though people are saying it is taking them only seconds to lock on. Hmmm.....

GPS Fix - new possible settings

This might be my first post ever, however, long time lurker on the boards.
I think I have a potential fix for the GPS issue with the Captivate. I don’t think this is the same as the “quick fix” found elsewhere on these and other the boards. I am not sure what (if any) 'side effects' there are to this.
My phone previously had the AT&T/Samsung fix from late September applied, although it didn’t seem to help.
Get to the Lbs test menu; previous available through *#*#1472365#*#*. However, if you previously installed the recent AT&T/Samsung (supposed fix) for the Captivate, you can’t get to the menu through the dialer. Use Anycut from market to get to the Lbs test screen.
My GPS now gets a great lock about 30 seconds.
BTW, I am not root….
YMMV. You should record your original settings prior to making these changes, just in case you need to revert.
Standard Disclaimer; I am not at fault for any issues this causes your device…..
Now, down to the settings that I use:
In Lbs test menu:
I “deleted GPS data”
Application Settings
– Session Type: Tracking
– Test Mode : S/W Test
– Operation Mode: MS Based
– Start Mode: Cold Start
– GPS Plus: Off
– Dynamic Accuracy: On
– Accuracy: 50
– Use Skyhook: Off
– Use PC Tool: Off
SUPL/CP Settings
- Server FQDN Type: Auto Config
- Server [leave what is autopulated]
- Server Port [leave was is autopopulated]
- Supl Secure Socket: On
- AGPS Mode: SUPL
Reboot.
Use GPS Test from Market, or the The “Get Position Test” menu from Lbs screen to validate.
WIFI Problem:
One thing I have noticed is that depending on the settings above, wifi (if on) sometimes inhibits the ability to see more than 1 satellite. I think the problems with GPS are overall related to Wifi in some way.
If you do not have luck with above settings, turn wifi off and see what happens.
I only had to change a couple of the settings but this is working nicely so far...Ill try again over the next day or so in various situations and report back.
Changed:
Op Mode to MS Based
Start Mode to Cold
Turned off GPS Plus
Secure Socket to off
Thanks!
I'll admit some of this seems counter-intuitive, but at this point anything is worth a shot.I'll let you know how it goes!

You don't need to download anything to access the Lbs test. Just type *#*#3214789650#*#* in the dialer and you will get access. Works with JH7 and Froyo.
Before anyone else reads this and declares their GPS fixed, they should read at least the first post of this thread completely. http://forum.xda-developers.com/showthread.php?t=789383 If you understand what is being said by that post, then you can offer GPS solutions. The only thing you have changed is AGPS settings. While those settings will get you a lock, they don't help out with accuracy. If you really want to test your GPS, you have to turn off the use wireless networks feature, take it outside and see how well it works then.
Everything that has been said in this thread has been said elsewhere and is not a solution.
Nope, it's definitely not fixed...but it did give me a better lock than before. Same old...
Sent from my SAMSUNG-SGH-I897 using XDA App
Well if its not a fix then it is most definitely better...I can get a lock in ~20 seconds where as before it might not even come close.

Additionally, a lock is not enough to say it works. Take it for a drive along with another GPS device - use Google my tracks or some other tool to record your path. Even use GPS test and watch your MPH, direction and location.
You will find that it is not fixed. It works OK sometimes, but many times it is behind or inaccurate.

Well if its not a fix then it is most definitely better...I can get a lock in ~20 seconds where as before it might not even come close.

You will have to do that every week as your cached GPS data expires. And you can literally use any settings as long as you can use the lbstestmode to accquire a lock. That's all you need to do (accquire your first lock and it will cache the data for 5 to 7 days).
Any "fix" that involves "settings" isn't a "fix" at all since it demonstrates an utter lack of what the real problem is and how GPS fundamentally works.
The real "fix" won't come in the form of settings. Any purported settings "fix" is snake oil.
I've given up on GPS a while ago.
It's a fringe feature anyway.
I never have "use wireless networks on" and gps works good enough. It may not be perfect but everytime ive used it it has got me where i need to go no problems. It may jump off track or be slow to turn for a second but it still gets me to wherever just fine.

If I read this correctly your turning off skyhook ? I read this http://www.skyhookwireless.com/howitworks/, and to me you need it turned on for urban areas and in the city need wi-fi turned on because of the occlusions caused by buildings and such...?

That option has nothing to do with GPS. 'Use Wireless Networks' is actually quite useful for location aware apps like Google Maps, Places, Speed Test etc. where an accurate but slow GPS lock may not be needed (or even possible if you're underground or inside a concrete building). This option enables those apps to use cell tower or wi-fi signal trianglation to get a quick estimation of your current location so that apps can give you relavent information, i.e. nearby gas stations or resaurants. It has nothing to do with aGPS either.

You have to be kidding saying its a feature right? I can't believe how many say that its a feature and that it is ok that Samsung is screwing them ( along with placebo updates) . I myself love and would like a Galaxy S phone or even the new Focus 7, but its looking like it too has GPS issues from early reports with the Omnia 7.
I know most of you guys are already locked in with your carrier and don't have much choice with the GPS issue but its not a feature, its a valuable function just like placing calls, sending emails, texting, etc.. If you don't care about this, then you should of bought a Razor flip phone.
I have been keeping up with this because I really want to see Samsung resolve this and make right.

So the only reason you need a phone is for the GPS? Otherwise just stay with my 1996 model flip phone? Just...wow!

I think their point is that it is an advertised function of the phone and we would like to work properly.

My reasons for a working GPS are as follows:
Pinpoint your location, get turn-by-turn directions to restaurants, businesses and other destinations, location-based mobile games, social networking sites, real-time position tracking, lost or stolen phone tracking, etc., etc., etc..
What I am saying is just quit making excuses for Samsung and demand what you paid for! There are people on here who would really like for their GPS to be working and rightfully so.
Oh, I agree that it should work as advertised. Can't say Samsung is ' screwing' me because they can't get it right. Would have bought the phone if I knew about it beforehand anyway. There are many other features that led me to the Cappy. Samsung does need to fix the problem and I hope they do so soon. Buy I won't try discourage anyone from Samsung products in the meanwhile.

The solution to the GPS problem is quite simple, but most people still don't see it.
If 100% accuracy and < 10 second fixes are more important to you than the rest of the Galaxy S features, then you do not want a Galaxy S phone. Either return the one you have or don't buy it. For most people, that good of a GPS is a bonus and not a requirement.
The GPS problems are not undocumented, anyone reading any reviews for the phone will realize that the GPS is not as good as other devices. Even if they don't realize it before they buy it, they have 30 days to return it. Samsung may or may not ever get the problem worked out since phones have such a short life cycle. *****ing about it in thread after thread, online petitions, and idle threats of legal action will have absolutely no impact on Samsung.

Standalone GPS on xv6700; Solved?

I want to say I love this site and have learned alot. I have tried for quite a time to get GPS to work on the xv6700, tho it seems much disinformation has been spread as far as a GPS being within. I have torn down this phone to see for myself if the MSM6500 was in this, which it is. Therefore I believe it does have this ability. I recently installed a program called WPS by Skyhook, which is a Wireless Positioning System. Now just a footnote; my phone has no carrier, I only use it for surfing the internet with wifi. To utilize WPS the site tells me I would need an active internet connection, however it stills works with no connection!!! It seems as if I have gotten the internal gps to wake up. I use Open Mobile Maps and it works excellent. I pickup satellites with Google Maps just to test at home (so far as many as 10 satellites). Can somebody else please duplicate this to verify exactly what is going on here? I just want to emphasize that this is with NO CONNECTION to ANYTHING!!!
