I had an iPod 2g that I'd jailbroken before but I restored it because of some issues I'd been having. The top button on my iPod stopped working so I took it to the Apple store and got it replaced. I got an identical 2g iPod. I don't remember if 3.1.3 was installed on it already but I think I remember updating it once it was at home. I really need to jailbreak it. I can't stand not having it jailbroken. I've tried downgrading it to 3.1.3 but it says that the file isn't compatible when I try to restore it from the downloaded file. I don't have a new iPod though, it's still a 2g. I tried resetting it but it still had 3.1.3 on it. Does anyone have any ideas as to what I can do?
