    Actually it is not true GPS but A-GPS. It's a sort of assisted GPS. It works by triangulating your position from cell towers in the same fashion a GPS uses satellites. It only works with 3G models in conjunction with GPS apps. If you fall out of cell reach, I'm pretty sure it won't work.

    the iPad has a True GPS. It is accurate within 15 feet.
    The iPad 3G is the model with GPS, wifi only ipad does not have GPS. Also like the poster above said it uses whats called an Assisted GPS. This means that it can find your location mutch faster than a normal GPS.

    First it uses the cellphone tower to get the city location for where your at. This means it knows right off the bat the general location/city your in and the actural GPS doesnt have to work as hard to pinpoint your exact location.

    If the 3G service on the ipad is disable the GPS will still function since it is a true GPS.


    As far as GPS software, it only comes with a google maps app. other GPS software is downloaded from the app store.

    You can download apps that do.

    Best one would be Navigon.

    There seems to be a lot of confusion with the GPS. I had friends tell me after I bought my iPad that A-GPS is inferior and not "true" GPS but relies on cell towers (like the above poster which was mistaken).

    Like the other poster above, A-GPS is "enhanced" and therefore sometimes faster than regular GPS as it uses both cellular and satellite. Satellite location will always be used as the primary as cellular triangulation is not quite accurate, however it speeds up the initial tracking to your region faster than the satellite will - in other words it "assists" the actual onboard GPS chip. Personally I have yet to activate my 3G and my GPS still tracks me within 30 seconds or less (unless way indoors).

    I have had a GPS location on my iPad when I have had cell no service with AT&T on my iPhone, so it certainly must be using satellites.

    And, here's a tougher question: since my iPad is wifi only, how could it be using cell towers anyway, unless it has the 3G hardware installed, but doesn't enable it for use?

    WiFi-only units use the location of the wireless network you are connected to.

    Oh, that's a good one. For a moment, though, I thought you were serious. LOL.
