I just got it to work, I'm not sure if i had to download metadata removr or not, but i did.
On your ipod/iphone, go to the appstore and download any small free app and delete it if you want. On your computer, open itunes and (your choice of a free app or song) I downloaded Paralyzed by As I Lay Dying cuz it was free (and they're AMAZING), but you can download whatever you want (again, delete it if you want). After that, plug your idevice in and on the side, right click on your device and click "reset warnings". Now if you sync it should be working fine.
