Any device that has been jailbroken in any way will not sync with iTunes 11. So people who have trouble syncing with iTunes should look at this as a possible reason.
There is no jailbreak for the 5th gen itouch, which is what i own.
Also for anyone having my issues or just don't like itunes 11
Use the Control Panel to uninstall iTunes and related software components in the following order and then restart your computer:
Apple Software Update
Apple Mobile Device Support
Apple Application Support
Here itunes 10.7: http://www.filehosti...64Setup_(1).exe
A How to recover you library after you go back to itunes 10.7 from 11
Now you will have to rescue your old iTunes library from your Music>iTunes > Previous Libraries folder and rename it "iTunes Library.itl" (replacing the existing one in the iTunes folder) because a newer version of iTunes irreversibly updates your library file. Note, this will revert your library to version at the time of the upgrade and you will have to update any changes made since.
