Hello there, I’m looking for a confirmation among you knowledgable ones. I got an iPhone 3G and would like to jailbreake it. It is officially unlocked by Apple. I jailbroke an officially unlocked iPhone Classic without problems using PwnageTool. Will there be any problems with 4.2.1 and iPhone 3G at all? I just want to jailbreake it. I dunno if there will be any repercussions on the official Apple unlock?
