So I jailbroke an iPhone 3G running iOS 4.2.1 using redsn0w 0.9.10 b6. Everything was fine and dandy until it asked me what I wanted to do with the jailbroken phone. I selected "Install Cydia." It gave me error 233 and quit. DiskAid 4.51 recognizes the phone, but I don't see a root folder. So the phone's owners now have an iPhone with a useless jailbreak unless I can install Cydia.
