    Default Bad ESN iPhone 4s Unlock for AT&T
    So I bought an iPhone 4S for Verizon off Ebay that has a BAD ESN.
    I was wondering if I could get it unlocked via the sam method or the gevey ultra?
    And if I could do it, could you possibly link me to a tutorial as to how I would do it for a bad esn or the gevey ultra?
    I want to use it for AT&T
    Thanks for any help.

    Bad ESN means phone was lost/stolen, AT&T will not unlock those.

    Bad ESN means nothing for AT&T. AT&T doesn't use ESN. So if he somehow unlocks his iPhone -- which he can using the Gevey SIM because his on iOS 5.0.1 -- AT&T will still accept his iPhone even if it has a bad ESN. Sprint/Verizon won't accept it though.

    I read up on this sh!t and AT&T doesn't use ESN and only IMEI, so if the phone has an ESN, its not an AT&T phone, but rather a CDMA phone. So AT&T cannot unlock ESN phones either way since its not an AT&T branded phone.

    I never said AT&T will unlock the phone. But he can unlock it using other methods other than AT&T, like a Gevey interposer.

    Why can't he unlock with SAM? I have seen on Google many success stories unlocking a Verizon 4S to work using SAM.

    The SAM method has been blocked by Apple servers

    yes it would work, but your phone must jailbroken on 5.0.1 and you must stay far far away from ios 5.1 or 5.1.1 because there aren't any jailbreaking tools for them yet
