I don't know if any of you guys are familiar with the vidcast "Geek Brief TV", but the hostess, Cali Lewis, is a Mac head and picked up the iPhone on Friday. I saw the Saturday show and she was saying she might take it back because of a misunderstanding about the terms for "unlimited data". She and her husband ended up keeping their phones, but said that when she called TMobile to cancel existing service, their reps knew more about the iPhone/at&t service terms than the at&t rep did. To paraphrase, "A response of, 'I think so', doesn't inspire a lot of confidence when talking to an at&t rep".
