When I ordered last night I choose the AT&T Version. I don't remember having to choose when I bought my iPad 1, but I think that's because AT&T was the only one available if I remember correctly. So basically because I've chosen AT&T they are the only one I can purchase cellular coverage with on the iPad? Or can I still choose one of the others? I'm thinking of ordering another one with Verizon as their plan looks to be better and cancelling the AT&T one I ordered. Can you tell me if I'm stuck with AT&T or will I be able to pick anyone that has iPad cellular coverage available?
