    I have a 3GS phone with an unlimited data plan. My current contract ends in just under a year
    If I bring in a (full priced) phone from Canada/UK or any other unlocked country, can I trim my SIM card to fit the micro SIM chip holder and then use the 4 on ATTs network?
    And then when my contract ends, on how many and on whose networks will I be able to use the phone?

    The US only has 2 gsm carriers, AT&T and T-Mo. Although iPhone 4 is penteband (?), T-Mo's 3G is on a band not built into the iPhone's radio. Not much of a choice.
