    Just restore it to 4.1 using a No_BB IPSW, choose set up as new, do not restore to backup.
    ITunes will apply the unlock

    You don't even have to restore to get the AT&T factory unlock. You just insert a foreign SIM and connect to itunes, a message will pop up saying your phone is unlocked on itunes.
