So I'm running 2.2.1 2nd generation 32GB, originally jailbroke last March using....Cyw00d (it's what's in my iPod folder under Jailbreak)? Now just recently my Cydia and other things haven't been working like they were (tons of errors and other bits and bobs not updating properly) and I want to re-jailbreak. What's the easiest way to do this? I've been reading around a bit, but haven't gotten a clear answer. I'd like to upgrade to the 3.0 firmware or whatever the newest thing is so I can finally use some apps I've been wanting to if that's at all possible. Thanks in advance.
