Really basic question about GPS in Androids... Monday I buy my first smartphone EVER... HTC Desire. Can't wait! Thing is.. I am completely green about the inner workings and have a question about the GPS... Basically how does it work? Is it just like having a GPS from Magellan etc.? Or is it based on cell phone tower triangulation etc. Thing is... it sounds like it is a seperate system that talks to a gps sattelite.. but that seems "too good to be true"... I can get a fully functional GPS in my cell phone???? I just pee'd a little. Also how well does it work outside major urban areas? I would love to take it hiking in remote areas.. but do you need a signal from a tower to use the gps or can it still use the GPS portion independant? Thanks.
