    I recently got o2 to unlock my iphone 4 which is also jailbroken on 4.3.1.
    However, I wish to update my firmware to 4.3.3 and then re-jailbreak with redsnow.

    The question is, will I lose my o2 unlock? :confused:
    Will I have to re-unlock with o2?

    Official carrier unlocks persist across any firmware updates, jailbreaks, etc - once your phone has been unlocked by the carrier, it's basically unlocked for life

    Thanks! So I can go ahead and rejailbreak,

    Do I have to activate the unlock again once I restore? With another micro-sim first?
