I bought the update this morning, and installed it tonight because I didn't get a chance to earlier. It said it was backing up my touch, then it installed everything. And yet, when I turned on my ipod after it finished installing, no music was there. It only synced what was on my computer, which was only about 1/10 of what I had on it before (I don't keep it on my computer because I don't have the space). I thought that it backed up my ipod touch? Anyone else have this problem? Or anyone know how to get my music back if it's not too late?
