There is a simple fix for that: use the phone's built-in GPS receiver.
I'm not sure if you have ever owned a GPS reciever, but GPS signals are very bad at going through solid objects. Getting a lock inside is quite difficult and when one is achieved it will not be very accurate (some inital testing on my GPS reciever inside my home reveals that the horizontal positioning error is on the magnitude of several hundred feet, not close enough to figure out where you are). That is why most cell phones use triangulation off of the cell phone towers to figure out where you are. It can be (and has to, legally) quite accurate, on my CDMA phone this is called gpsONE (despite not actually being GPS). I have made some test calls with it and the coordinates it gives me are dead on.
