    Contact AT&T.

    Just because the device is elligible does not mean it is unlocked.

     

    Nothing in your posting indicates you actually contacted AT&T and requested it be unlocked.

    If you updated but did not restore after updating then your phone was not unlocked. You need to restore the phone to the CURRENT version in iTunes. You should see the message "Congratulations! Your iPhone has been unlocked" from iTunes.

    After updating it restores the backup, but does not reactivate the phone. The reactivation step is required to unlock the phone, and the only way to reactivate is to restore again. If you never got the "Congratulations" message the phone was not unlocked.

    Then it has not been unlocked yet. You can wait a couple of days, or call AT&T.

    If your phone was ever jailbroken it probably cannot be unlocked.

    Can you expand on that statement? Why would a previous jailbreak mean you can't do the official unlock? Part of the official unlock is a full restore to factory settings isn't it?

     

    I have a 3GS that AT&T say they have completed the unlock on, but when I go through the restore procedure it ends up at an error saying "There is no SIM installed". There is a SIM in it, and I've tried several SIMs all of which give the same error. Surely it doesn't have to be a current live AT&T account SIM to complete the process?

    This is a phone that used to be on my AT&T account but when I upgraded to an iPhone 4 this was retired. I have used it as a jailbroken phone, but it is now on a fresh install of iOS5.


    Trust AT&T to make the official unlock a long and confusing process even when they eventually give it to us....

    Jailbreaking the device modifies the baseband.  Not all software updates require an update to the baseband and this is the only time when a baseband would be overwritten.

     

    As a result, if the device has been jailbroken and a subsequent iOS update did not force a baseband update, then it's very likely that an official unlock will fail.

    Thanks. Is there a way to force the baseband to update? I guess all the jailbreaking tools are designed to avoid this, so maybe not.

    If I can find out what the baseband is, can I match the OS version and do the official unlock from there?

    This far into the process, it seems that the best option is to stick with unofficial unlocks (not that that was easy for me).
