I've been searching for quite some time, but I am still confused. I am using an unlocked iPhone 3G v3.0.1. Jailbroke with redsn0w, unlocked with ultrasn0w. Do I need to jailbreak again with the new Pwnage Tool? If I do so, will I lose the unlock I already have? I am currently living in Europe, and if I lose my unlock, I'll be left with no phone, so I'd rather do this right the first time! Thanks!
