Fix your iPhone 3G GPS problems – 3G network issues with iPhone GPS

The new GPS hardware in the iPhone 3G seems to be having some trouble when not connected to the AT&T (NYSE: T) 3G network. iPhone Atlas reports that some users are complaining of inaccurate GPS positioning when the 3G data setting (Settings>General>Network>Enable 3G) option is switched to “ON.”
The iPhone 3G uses aGPS (assisted GPS), which means that the cellular network aids in positioning the handset, giving the GPS hardware less number-crunching to deal with. That means you get super-fast GPS lock-on times. But, it seems that some iPhones are getting conflicting data from the 3G data network and their built-in GPS receivers, leading to incorrect GPS positioning.
So, for those of you with wonky GPS positioning on the iPhone 3G, try this fix:
- Navigate to Settings>General>Network>Enable 3G and toggle to “OFF”
- Locate yourself using the iPhone 3G’s GPS receiver
- Navigate to Settings>General>Network>Enable 3G and toggle to “ON”
You should now have accurate GPS positioning information. Leave a comment if this worked or didn’t work for you.

That didn’t work for me. I am now 25 miles from where it showed originally.
This solution did not work for me. Anybody have any other ideas?
Both my iPhone 3G and my wife’s started showing is in Portland Maine in stead of southern MO. Started sometime on Wed. I never realized how much I use the location feature until now. We are nit in a 3G area but I tried the fix suggested above with no change.
Any ideas?
I’ve been trying to fix mine for 11 months and finally did it, by turning on Wifi (I usually have it turned off). Even not connected (I don’t use Wifi at home and all neighbours have their signals passworded) it still works. I remember the one time it worked for me in the first 11 months was when I was abroad, on a motorway /highway I noticed it was tracking my position dead accurate and moving in real time. I never figured out until now why it worked there and not at home. I was using Wifi in my friend’s house there, hence kept Wifi set to ‘on’.
I tried several things to solve problem but i have to mention that this problems I have since I upagreded to 3.1.2.
because my 3G has aGPS it google maps locate me only probably over the cellular mobile. Of course the location is not accurate at all. it shows the blue point somewhere near me, sometimes not even that and it don’t locate me exactly but it make a blue crisle with 1-2 km of radius.
What did i try to solve problems but it didn’t work.
a) to turn off 3G and locate myself
b) to turn on Bluetooth when trying to be located
c) delete cache for gps positons over terminal or over SSH
any new ideas what to do?
This worked great my iPhone was saying I was like a mile away from actual position and now it works fine thanx
I’ve heard that the gps sattelite were not going to be replaced soon enough due to shuttles grounding in 2007… or was it in 2007?
The fix doesn’t work for me — with 3g on, I get one inaccurate location. If I turn it off, it indicates a different location (also wrong).
I never had these problems until I upgraded my 3g iphone to the 3.0 software. Ever since then, I have had nothing but problems with this phone. Problems with the calendar, problems with gps, problems with dropped calls, problems with failed calls. The thing went from perfect to garbage with one software update.
Some of the trouble could be related to ATT’s network. I think I’m going to move to Verizon’s Droid. New network, new phone.
