Was I the only one watching the iPad announcement? Uncle Steve specifically said that the iPad would NOT be locked to any carrier, and that you can insert any old micro sim from any carrier for it to work.
AT&T are the preferred network, and iPad will have a way for you to buy 3G credit directly, but that's a convenience feature. Any 3G iPad will work with any 3G network provided you can get a microsim.
