    Default sim card not installed, cant jailbreak or restore help !
    hi i am from the UK. I have jailbroken iphones before. So i bought a iphone 3gs 16gb from the USA and received it today.

    The seller has told me it is on at&t but he doesnt know what firmware its on and doesnt no weather its old bootrom or new.

    So i dont have a at&t sim, and the iphone is bricked.

    I have tired blackrain, restoring in itunes using 3.1.3 and 3.1.2 and have also tired creating one in snowbreeze.

    I keep getting a itune error each time , a different number as well

    Please can someone help


    thank you

    also i dont think it has been jailbroken before , so that means i cant use the snowbreeze method ?

    so i figured it out, so my firmware is 3.1.2 I unlocked with blacksnow , but i am getting no service.

    Is this because the modem firmware is 05.12.01, if it is what should i do ?

    please help



    also according to my serial num: it was made in the 39th week.

    but my model number stars with MC

    do i have the old bootrom ? should i upgrade to 3.1.3 and unlock ?

    you are getting no service because 05.12.01 is not unlockable at this time...

    on the 3gs once your baseband is updated there is no way to downgrade it so as of now you are stuck
