I don't think there is enough room in a phone for a true GPS reciever. If there was, GPS receivers would be much smaller than they currently are. If they could be smaller, they would be. Best test I would recomend would be to try the GPS function when you have no signal. Battery useage is no indicator of what it is really doing. Roaming burns through battery because it is doing more work. Any kind of signal booster will burn the battery fast.ranwin33 wrote:kellory wrote:My company just upgraded me to a smart phone, and it has google maps allready on it, and it works fine for roads around town, and seems very accurate.

I think your phone GPS is using satellites - at least my Sprint phone says it is looking for them when I turn the GPS on and it requires a view of the sky. It also will track location through w-fi settings, but that is not the GPS.
Using GPS on the phone is different from the GPS Sprint uses to determine location based upon cell tower triangulation. But using it uses the battery up pretty quickly. At least that is how it works with my HTC Shift, I think.
