The Diablo is about to hit the streets soon (2Q08... and no, it doesn't have to be the last day of 2Q...) and we'll get the A-GPS support that supposed to improve the performance greatly. I'm running Diablo and have this A-GPS app installed. However, sometimes it seem like help a lot but sometimes I do not notice much if any improvement. (But I have not really used it much... I rarely need the GPS and map.) Maybe someone else who has Diablo and A-GPS app have more experience?

Another detail I remember that in the "beginning" there was some A-GPS data stored into a file in the internal memory card... but lately that file does no longer exist. Has anyone else seen that too?
