    Sounds like the activation process is a pain in the rear. Any reason I can't just pop my iPhone 4 sim into the new phone and restore from a backup?

    it should work fine, however not sure if anything has changed sim technology wise to support the higher speeds?

    hmmm... good point, although I think that's just the radio in the phone.
