That said, aren’t you Americans always gonna be out of luck? I thought the iPad’s 3G only works with AT&T, the best you can do if you don’t want AT&T is get Edge and T-Mobile. That must suck.
It looks like maybe not?
The iPad supports UMTS/HSDPA (850, 1900, 2100 MHz). at&t operates on 850 and 1900 MHz. T-Mobile operates on 1700 and 2100 MHz. I don't know enough about modern cellular technology to know whether that means they'll have 2100 MHz towers in most or all service areas where they support 3G.
