I have a 2g MC model of the touch which was jailbroken using jailbreakme.com last night. I was able to install my old jailbroken apps, but upon connecting it to iTunes, a sync deleted all of them, and gave me the message about authorizing my computer to even transfer the legal purchases from the appstore to itunes. Is there a loophole around this? Alternatively, what other programs exists which can sync independently of itunes for mac?
