    Hi I would like to update my iphone that is jailbroken and unlocked from 3.1.3 to 4.3.3 without going to 4.3.5 while preserving the baseband 05.12.01 so that i can continue keeping it unlocked with untrasnow. Please help me i'm new to this and need a step by step process including activating later on without original sim card, also please include the place for me to download the software. Thank you so much in advance.

    At the iPhone hacks section.
    You will need shsh blobs for 4.3.3 to restore to that.
    Open cydia and check if you have them first.
