For some reason when I try any type of sync it does not sync. Like for example, if I download a new song, and press the sync button, or manual sync, nothing happens after it is done syncing. My 2G iTouch is Jailbroken, it is I think 3.1 or 3.0 firmware, and my iTunes version is the newest. Is it just me, is it my iTunes, or is it my iTouch? Please help me. Thanks in advance.
