    I have an iPhone 3GS running iOS4.3.3, jb and unlocked. My friend is helping me to get ATT to unlock it. My question is will the ATT unlock procedure works with my jb image or do I need to first install an ATT image? I plan to upgrade iOS to 5.1.1 anyway.

    At the iPhone hacks section.
    You can stay at 4.3.3, deactivate it with redsnow then activate with any sim and remove ultrasnow or update to stock 5.1.1
    Currently 5.1.1 is a tethered JB for the 3GS.
    Up to you.
