    Ultrasn0w can not unlock iPhone 4S according to my knowledge.
    There is no unlocking tool available to unlock 4S so fAr.
    You can unlock only iPhone 4 and predecessors with ultrasn0w.

    as i said. ultrasn0w can not unlock iphone 4S no matter which firmware you have... so its pointless to downgrade your iOS ... forget it.
    try GEVEY SIM to use any SIM card on your locked 4S.. there is no other solution for your phone.
