    I am planning on unlocking my iPhone 4 soon and getting a pay as you go SIM card since I will be leaving the country, but the only problem is that I have a year left on my contract with AT&T and would rather not pay the early termination fee.

    A relative has an iPhone 3G which has been in contract for over two years and so could be cancelled. Would it be possible to cancel that contract, take the SIM out of my iPhone and use a MicroSIM to SIM adapter to be able to put it in the 3G, and would this then continue my contract on the 3G without any issues? Could the 3G resume my contract without having to be unlocked and without AT&T knowing my phone has been jailbroken and unlocked after taking the SIM out? I've looked but haven't found an answer to this particular question. Thanks a lot.

    This would work, you don't need to tell at&t when you change phones, but don't you still end up paying the monthly fee for another year while you are abroad? That's like $800. ETF seems cheaper at ~230$ Plus you will get the iphone 4 unlocked from at&t.

    Well my relative would take over the plan and keep using the SIM so I wouldn't be paying for it. And it's only $25/month with a family plan. But that's good to know it would work. Would it be possible to get the number of the 3G switched back to the original number after the new SIM is put in?
