Hey guys. I wanna try jailbreaking my 3g iphone. Everyone has told me not to since I have ATT but since the iphone 4 came out I want to try it. I plan to upgrade to the new iphone 4 in like a month or two. I'm gonna sell my 3g to radio shack for 100$ or whatever they offer when you upgrade to the 4. But for the next month or so I wanna see what jail breaking is like. What is the best/ easiest program to do it? I want one that is easily reversible. Like the one what resets itself if you like restart the phone or whatever. What do you suggest? Anyone think I shouldnt do it? btw, idk if it matters but I am running ios4 currently on it.
