I've jailbroken and unlocked many itouch and iphones to date. All working fine. Used ownage tool and blackra1n ect. So I understand things fairly well. However..... I will cop a new 3gs 32gb tomorrow. It comes unlocked (buying in China). I use a Vista PC.... I will want to jailbreak it. I know Blackra1n will leave me with a tethered jailbreak. Fine. BUT will it effect my unlock? I do not use AT&T obviously. I can't find a clear answer on this anywhere. I only read Blackra1n will only work if you use AT&T. That sounds like it will screw up my unlock. OR, is there an option to jailbreak/unlock this 3gs with pwnage on my Vista PC?
