iPhone 3G GPS Not Working - How to fix it
Sunday, July 13, 2008
There have been many reports of the iPhone 3G having problems with its GPS positioning. Many users are reporting that they go into Maps on their new iPhone, click the target to lock onto their position and it is just not working. I too was experiencing this and have three things to advise, that may point to a solution.Firstly, check the version number for your 2.0 software. Mine was factory shipped with 2.0 (5A345). I did a restore through iTunes and it downloaded the later 2.0 (5A347) version. After this was downloaded the iPhone got a cellular signal a lot quicker, plus a lot stronger signal too.
Secondly, check you at least have a cellular or mobile phone network signal. The iPhone (both 3G and first generation) use the cell network to work out your position. I found that once I had a four bar signal or more, the iPhone locked onto my position very quickly. It was not that accurate, but it did respond quickly.
Finally, put your iPhone 3G outside for at least 15 minutes. You will find that if it has a non-restricted path to the satellites you will get it to lock on. After leaving mine outside, the target changed to the blue glowing dot and found my position. It was very very accurate, even tracking if I was at the top or bottom of my back garden. This is very impressive indeed.

Thanks for the tip. Sorted it for a little while but now back to being flakey!

Left lots of posts on apple discussions.
Hopefully a fix will be provided soon. -

My iPhone 3G, when indoors, seems to insist that I'm in Seattle Washington all the time. (I'm about 3,000 miles east of there.)
Outdoors... it seems to locate me fine (Michigan).
Would that mean "GPS Signal" is working... but ATT 3G and Wi-Fi GPS... are not?
(I have a strong 3G signal, and a strong wi-fi signal.) -

I may have found a solution. I live in Canada and have the same problem with iPhone 3G with original factory code (5A345). To reduce usage on battery, I and my colleagues turned off WiFi.
It looks like the iPhone GPS software needs WiFi enabled (do not require to be associated to AP). Turning on WiFi and going to Maps, now works both inside (very close to our location within 20-50 meters) and outside including getting the blue dot (outside 5-20 meters).

What is "AP"? -

Carol, I think that in this case AP means access point- in other words, wifi needs to be on, but you don't actually need to be connected to an access point.

Wow... that's REALLY odd.
You are saying: Wi-fi "needs to be on"... but even if "not connected"? (So it's not even getting ANY 'location info' (right or wrong, info) from wi-fi... but it still needs it 'on'?)
I found out something more: If I turn off 3G... the GSP works all the time. -

Since I installed v2.0.2 all my GPS locations seem to be working 100%.
(Regardless of whether I'm indoors/outdoors, using EDGE, 3G, Wi-Fi, etc) -

Why do you have to get a phone signal to use GPS? I mean if there is clear site to sky, why can' t iPhone GPS work just like a car navigation system?
