    I'm on a 3GS right now with 4.2.1 and 06.15.00 without ultrasn0w set for the unlock. Unlock isn't important. But what's the process I need to go through right now to get up to the current iOS version?

    From what I recall I think I need a modified .ipsw that doesn't change the bb, right? If anyone would be kind enough to maybe give me a step or two beyond this, that would be great... thanks!

    So I'm basically downloading the official 4.3.1 .ipsw and then loading up PwnageTool and then saying 'No' which will then give me a custom version?
