So I have an Ipod Touch 2G, currently NOT running 3.0, but jailbroken on the latest free update of 2.2.1. So when I first jailbroke it, it did not work on my computer, and I had to give it to a friend to jailbreak. If I upgrade to 3.0 then try to jailbreak, and it does not work, is there any way to go back to my current jailbroken 2.2.1 Ipod? I'd quite honestly rather have a 2.2.1 jailbroken Ipod touch then a 3.0 non-jailbroken Ipod Touch. Don't mind losing the $10 if it doesn't work, but want to make sure I can go back to my current form if it doesn't work. I'm running Windows XP, if that makes a difference.
