    GPS
    Assisted-GPS

    Copied and Pasted from apple's store. Anyone care to elaborate on the differences between GPS and A-GPS? Also, discuss the fact that the GPS is actually A-GPS.

    A-GPS = GPS + assisted positioning via cell tower.

    A-GPS > GPS

    It uses a GPS receiver and also aids tracking by using cell tower triangulation etc.

    i'm a little slow here -- does that mean those of us with the current iPhone will get pushed aGPS with the upgrade?

    No. You still need a GPS chip for A-GPS.

    Not sure, does the current iPhone have the GPS chips?

    One quick note about that link. It has a mistake. When they say:

    No, not every phone has an aGPS chip on it. E911 does not mandate the use of GPS, only the ability to locate a percentage of phones in each area, by whatever means you wish.

    I don't see why not, assuming the GPS is truly independent.

    Yes. You'd need wi-fi or a data plan to use the maps aspect, though.
