    Hey guys, A few months ago I recieved an iPhone 4 that is supposedly factory unlocked. I really want to update to the newest firmware but I'm afraid of potentially loosing the unlock. Can someone please tell me if my iPhone 4 is factory unlocked?

    Here are the specs:
    Version: 4.3.5 (8L1)
    Carrier: Carrier 10.0
    Model: MC318LL
    Serial Number: 61131UZWA4s
    Modem Firmware: 04.10.01

    Note: I found a list of factory unlocked phones but a few people have told me that list isn't up to date.

    Note 2: My Model is missing the (/A) at the end of it.

    In that case, it's not using some unauthorised unlock now, so it should be fine to update.

    BTW, which carrier are you using this iPhone on?
