Is AT&T able to detect you tethering? Or, if I tether, will I get a huge data bill even though it's "unlimited"?

  I find it more and more difficult to believe that AT&T would be able to tell the difference without looking deeply at the traffic; the iPad loads full web pages and videos, so they probably couldn't tell from bandwidth alone.

    Accessing YouTube, App store, maps and various apps should be pretty obvious.

      Third party apps can access the network too. So they'd have to distinguish between traffic generated tethered from traffic sent in 3rd-party app store apps.

        I was just thinking of plaintext traffic through port 80.
