I have a just-recently jailbroken ipod touch 2.2. I'm quite sure I successfully jailbroke it because there's Cydia. However, my itouch went into (I think) the DFI screen where it says to connect the itouch via usb to itunes. Then, I had to manually turn it off and turn it back on..... So I have no wifi so I can't tell if I successfully did jailbreak it. Is there a way to verify it? Back to the actual question: do I have to worry about anything? What about updating my ipod touch: if I update it, will everything be deleted? Or can I just update every single time with no worries? Do I need to jailbreak more than once or is this my last (hopefully) time? Thanks in advance!
