Ok this is a good question since i was struggling with Google maps this last week and i finally get it to work 10 minutes ago... Now the question: How the F... does my cellphone knows my exact location (marked with a blue dot) if the GPS is not equipped in this model? I live in Venezuela and here Google maps does barrely knows the name of some streets and doesn't give directions at all... I never wrotte my address in any way at the phone since it has only 2 weeks and don't know how to explain it... Any of you know how this is possible?
I don't see it possible.... so google maps knows the exact location of each one of the cell towers of all cell companies? and does triangulation on each device? that's less than possible IMHO but i would be glad to be probed wrong
True, it's the cell towers. The technique is called "trilateration" and uses intersecting spheres to calculate your position. The more spheres, the more accuracy. Navizon adds wifi access points. But it will never match the 3 meter accuracy of GPS.

Look in the GPS forum. I have and use BT GPS with my Flip, usually have to start BB Maps so phone correctly inits GPS, then start amAze or whatever other software.
