I've been reading the stickies and from what I see, they all seem to assume that you're already on 1.4... hence this post. I'm only on 1.1.1. I jailbroke and unlocked the SIM on my iPhone (original) way back last year, and just left it like that - if it ain't broke, don't fix it. But now I think is a good time to catch up with all the benefits of 2.0... Will the Pwnage tool take me all the way from 1.1.1 to 2.0? And how will it affect the SIM unlock?
