• I'm not sure of your platform (android, iphone, etc.) so this might not apply. I was having troubles getting any sort of GPS data in the android emulator. Even the built-in maps app wouldn't show a location. I found a way to set mock coordinates that solved my issue. Maybe it will help you?

  First, open ddms (Dalvik Debug Monitor). On Windows, navigate to the android-sdk\tools directory and run ddms.bat. The first line in the top-left pane will read something like "emulator-####" such as emulator-5560.

  Open a command prompt window. Enter 'telnet localhost ####' substituting the number you found above. This will open a telnet window to your android emulator.

  Enter the following command (substitute your own longitude & latitude, in that order, if you'd like):

  geo fix -82.411629 28.054553
  

  The GPS icon will appear in the emulator's notification bar. Geolocation is now available. At this point, I could get location data in my app and in other apps, such as Maps.

  You don't have to leave the telnet session running. Closing it doesn't turn off the GPS.

  I hope this helps.

• +1 - I'm having this problem too.

• Hey, I am still having the same problem. It only happens on 3G. For some reason, the callback for getCurrentPosition does not get called at when I am on 3G, works perfectly on wifi.

  Any help is greatly appreciated.
