Itunes 11.0.2 won't sync iphone(iOS 6.1.2) or ipod(iOS 5.1.1)
Since I upgraded to iTunes 11.0.2 I am not able to sync my music with my iPhone 4. At first I thought it was a bug in iOS 6.1.2, but today i tried to sync my iPod Touch (3º gen) with iOS 5.1.1 and it has the same problem. iTunes syncs my apps, but when it gets to music it just finishes the sync. I restored my iPhone, and now i have the same iPhone (with the backup copy) but without music, since it does not sync.
iPhone 4, Mac OS X (10.6.8)
