Hey guys, I have two iPhones here running 2.1 and iTunes 8 and they can't backup. It gives the error "iTunes could not back up the iPhone "X's iPhone" because the iPhone disconnected." Both phones are jailbroken. I also have a friend with the first generation iPod touch, also 2.1 and jailbroken, with the same issue. Could this be a jailbreaking issue? Are there people with non-jailbroken 2.1 software having the same problem too?
