If you have maps installed on your pda then data is NOT NEEDED, and Cellular service is also not needed (unless your in an area where youre not in satellite view and thats when a-gps kicks in and it will use the cellular towers for triangulation) MSM 7500 chip works as a Standalone GPS just as any Garmin, TOMTOM, MIO...ect would. It is no different, and just as these, the Touch need no cellular service or data connection in order to use TOMTOM, GARMIN or any other navigation app that already has preinstalled maps.

LOL The purpose of my explanation is to understand how A-GPS and Your carriers role of implementing it. I am not talking about just 1 device. I am talking about the whole A-GPS technology on mobile devices. There are exceptions. It's so funny people starts reading at the last posts then think that they already know how the whole thread went. It is so funny.
