iTunes library not syncing on iPhone4 with iOS 7.0.4
Since the update to iOS 7.0.4, iTunes on my iPhone4 will not sync. It says it's syncing (I've tried syncing both wirelessly and with USB cable) but nothing changes. I've tried making a new playlist and moving songs, toggling things off and on, rebooting my MacBook Air, rebooting iTunes, and rebooting the phone, but it's not syncing. My iPad music library is syncing just fine since the iOS update so this seems to be a problem with the iPhone4.
