    Hi,

    I have iphone 4s which was bought at full price from apple store in US. At the time of activation it did gave a message of being unlocked.

    Currently, I am out of US, so can I update to 5.1? Will it again ask for AT&T sim?.

    I do not want be stuck, hence is being bit cautious.

    Please advise

    Thanks

    If you purchased an unlocked iphone outright from the apple store it is permanently Unlocked and will stay unlocked. Just plug your phone in and update it, there is no harm in doing so.
