I think the aGPS on this phone only works inside of the Sprint Navigation app due to the lack of CDMA triangulation support in the OS. Any other app (Google Maps, etc.), needs a clear sky view for the GPS signal the GPS seems to be weak on this phone) or a WiFi connection or it simply will not work.

I guess whatever piece of 1.6 samsung hacked into 1.5 to get CDMA support on it left out the aGPS over a CDMA network. 1.6 or 2.0 or a cooked ROM cannot come soon enough.
