I guess if Spr0ckEt is right, it kinda sucks that it can't track you if you start moving, but an initial location is better than no location.

First of all, go back and read where he said "e"GPS. Not "a"GPS. Secondly, aGPS will never be better that stand-alone GPS. You need to go back to GPS school for GPS v/s aGPS and look at triangulation v/s transponders and how many you need and how close they can pin point your location of within feet v/s yards.
