Hi, I had purchased an iPhone 3G while I was in US. I used GOogle Maps extensively while I was in US and had no problems whatsoever. Now I'm back in India, and I've jailbroken and unlocked my iPhone, however now it seems that the Location tracking via GPS does not seem to be working. Trying to locate me in Google Maps or any other location based app ( 4square, GoWalla for example) results in an error message being displayed "Your location cannot be determined. Any ideas how I can fix this ? I've tried resetting Network settings, switching off and on location but to no effect.
