Can I complete the unlock process with AT&T for my iPhone 3Gs using the original sim card rather than another carrier?  My purpose is to unlock the phone and use it out of the country with a sim card from that country's carrier. 


Also, is there any way short of contacting AT&T or Apple (Apple store) that I can confirm the unlock process is complete and successful?  I followed the instructions but have not seen anything to confirm the unlock is effective. 


Thanks in advance.

iPhone 3GS

    Peter, thanks for the link but I've been there.  My questions are not answered in that link.  Thanks.  Any wisdom from the U.K.?

    Not that I am aware of ,We have been unlocking iPhones in UK for at least 3 years

    and frankly the only way there has ever been is to try another sim

    Know anyone visiting from outside US and could try their sim ?

    Is T-mobile GSM ,if so try one ??

    Hello there,

    I have a similar question.

    Once I've unlocked using a different sim am I then locked into the network of the new sim or can I change sims/networks whenever I like?

    as one of the other repliers indicated (implicitly) - you can complete the unlock using your original sim card - to complete the unlock you have to restore the phone in itunes - if its unlocked you should get a message from itunes that says


    Congratulations your iPhone is now unlocked


    but the only way you will really know it worked is to use a different sim card


    that what i did - i


    1) restored the iPhone with the original sim card and got the congratulations message

    2) installed a pre-paid sim card from another carrier and made an received a phone call

    Used SIMs are super cheap. AFAIK, they don't need to be active in order to unlock. You can probably get a T-Mobile SIM for a couple bucks on eBay.

    Thanks all.  I will need to contact AT&T and perhaps Apple.  I followed the process but did not get the unlock message from iTunes.  Stay tuned.
