Ok, i have a jailbroken ipod touch 1g 2.2 firmware. I was planning on selling my ipod to my friend, but he was unsure about it, so i let him borrow it. None of my music is bought from iTunes and neither is his. My iPod is on manually manage music mode. So when he was trying it, all he did was add some songs. The next day he said he would take it, and everything was working perfectly at the time. Once he got home and plugged it into his computer for the second time, he found that all the music and videos on the iPod are missing, but in iTunes, the music and video bar have disappear, and in its place was a 5.5gb "Other" bar. Apps still work too. I don't want to restore it or unsync the apps, because it took me like 2 days setting up the settings so he would buy it.
