Basically, aGPS is assisted by cell towers to speed up triangulation, or allow a fix to occur when only two sats are acquired.
This is different from the cell-tower based location in the sense that it only uses the cell tower information to provide GPS. All cell towers are equipped with GPS for timing among other things - and this is the information that it's relaying.
So it's not truly GPS or even aGPS. Your phone is NOT using GPS satellites to get a direct fix on your location. Does that make sense now?
The reason I'm convinced it's not using GPS is the devs have not sorted out how to get the information from the GPS receiver to Android. They need a driver for the linux kernel, and to my knowledge have not made much progress on it. Essentially if linux isn't understanding the hardware, Android will never get any information from it.

thanks for clearing that up. i never thought it was direct though, that's why i didn't try any navigation with it. it was just nice to use on the few apps i was using that i didn't need accuracy to x feet to be effective.
