when I try to sync my phone (4s running 5.0.1) I get a message on the phone saying that 1056 songs could not be synced. see iTunes for more information 1. there is no notification on iTunes 2. I have tried 3 restores, it still only syncs 2 of 10gb of music 3. I have tried reinstalling iTunes 4. I have tried to delete all of the music then re sync, manually manage music, convert it 188 kbps, and sync only checked. I have tried those all individually. does anyone have any idea how to fix this.? ps the vast majority of music was purchased from iTunes and it is an authorised machine.
