Hello! I've got a legit iPhone 3G so far, haven't jailbroken it. I hear people saying that you only need to Pwn it once, and once it is Pwnd you can just load the stuff on it easier. Exactly what has changed? I for one want to keep my warranty, so if there are traces left behind in the jail break process that's no really good, since jailbreaking could void the warranty. Anyone know how it really is?
