    What baseband is it on ? You can unlock 4.3.3 but im not sure if you cant downgrade your baseband unless you saved some files first .It is possible to unlock 4.3.3 but there is facts you need to know first

    Basically: if baseband is 1.59.00 you can unlock with ultrasn0wthe baseband matters more than the iOS version. If not you can buy a Gevey SIM to unlock but it probably won't work on iOS 5.

    Just google it. It's something you insert with your original SIM card that lets you unlock. Beware, Apple has so far blocked it on ios5.

    You can upgrade to iPad baseband 6.15 but it will void all warranty n it can't be undone n u will always have to have custom Ipsw if u want ios5 u will have to wait till snowbreeze releases a JB to upgrade to iOS 5 and if you ever press restore in iTunes it will hang your phone n will have to reload the custom Ipsw this way is not recommended but it is a option

    You can buy a gevey sim on Ebay. Thats what I used to unlock my phone thats locked to AT&T and cant be used here in Australia. But at the moment, I am not sure if the gevey sim is the thing that is stopping me from having the camera icon in my messages so I can send photos in messages. Probably will restore and do it again, see if it is that the problem. Will let you know
