Hi, I just updated my iPod touch from 5.0 to 5.0.1 and used redsn0w to do the untethered jailbreak. It seems like I messed up during the Cydia setup or something, and ever since then I couldn't find the Cydia icon. I rejailbroke it several times but still can't find Cydia. What else can I try?
I think your best option would be to restore and then try to jailbreak your iPod touch again to make sure it was done correctly.
