A GPS fix is made up of a couple of steps (simplified). First the receiver has to determine where it is on the planet roughly so that it knows what GPS satellites it should be getting a signal from - this satellite positioning information is called ephemeris data and takes a good chunk of the fix time to get hold of. With A-GPS it is this ephemeris data that is being sent to the handheld device based on the rough position of the cell tower(s) you are connected to - no complicated cell tower based technology is being used to position the device. However, because the ephemeris data is served up quickly the device gets straight onto some complex integration of signals from the known satellites to determine exact position and altitude (if you have 4 or more satellites in view). Hope that demystifies the process for readers out there. A-GPS works a little differently to what you are describing in this article. A GPS fix is made up of a couple of steps (simplified).

They have to actually learn the network though ... so it should get even better over time. I believe that it uses the Cell-ID which is listed on the tower and gives a relative location back.

Or rather the amount in KB, as data plans may vary, of course? Any word on the costs per data transfer? Or rather the amount in KB, as data plans may vary, of course?

Which is brilliant. And yes, they've got their own server, but there's a place in the phone settings to change the server if you want.
