    Clearly no aGPS according to apple specs but I get the impression it uses something beyond just wifi geolocation because when I call up maps, it's almost instantaneous, precise and the small gps logo appears on the top right!
    The iPad 2 was much slower and imprecise in comparison, what gives?

    If you have location service enabled, especially features like "find my iPad" our location has already been recorded before you open the maps app.

    The icon is for location services, not GPS specifically.

    No it doesn't have a GPS. But using wifi access point triangulation it sort of can give a position.

    Hold up. How exactly does using wifi work? I purchased my new iPad when I was in Guam, and turned off location services after playing with the map a bit. Now, I'm in my home in Japan, with a U.S. IP address (via a VPN service my router sends everything through) but when I just turned on location services and opened the map, it showed me EXACTLY where I am in less than3 seconds!

    My iPad is the latest model, 64GB wifi only.

    Your IP is still JPN that's why you're iPad picked up your location as JPN. The VPN is just a secure tunnel for you to do work remotely to access corporate resources.

    The WiFi only iPads use location services based on IP address. The same thing works when using Google maps on your PC or Mac browser.

    Given you only have the WiFi iPad that does not have GPS and is only using cellular tower and WiFi triangulation it is not showing you exactly where you are. GPS is much more accurate than cellular or WiFi triangulation and would be considered exact when compared to them. Consumer GPS is usually considered accurate to within 10-15 meters.

    No, my ip address is a US IP address, just like I said. ABC, CW, Netflix, you name it, have no problem working for me.

    This is wifi only, again, so there's no way cellular triangulation has anything to do with it.

    On a WiFi-only iPad location services works by accessing a database of router physical locations. This database is accessed by using the MAC address of the router. Note that you do not actually have to be connected to a router for this to work.

    This has nothing to do with the IP address that you are using.

    Nmea?

    Will the WiFi only iPad be able to use the GPS capability (streaming NMEA) of the Novatel MiFi 4260L? If so, will the normal GPS applications like Garmin or CoPilot work with it or would they have to be re-written to accept the NMEA data stream?

    As soon as it's jailbroken, you'll be able to install the GPS hack on it to connect to external GPS receivers over BT. It works flawlessly on my iDevices.

    Well, you might havebthat impression, but nonetheless, it does not have any kind of GPS chip, period. This topic has been done to death.
