    Your iPhone was probably locked to O2. Contact O2 about

    unlocking your iPhone. Only the carrier to which the iPhone

    is locked can unlock it.


    If your original receipt showed the iPhone as unlocked, pursue

    the matter with the seller.


    If the iPhone was purchased at CarWarehouse, it locks to the

    first carrier used.
