I've got a iPhone 3GS running 4.0.1 and mac OS 10.6.4, iTunes 9.2. iTunes just won't let me sync my photos. I've tried to reinstall the 4.0.1 firmware, reinstalled iTunes but it doesn't work. I had this problem before when I tried to add a picture to the iPhone - but it didn't let me. So someone said - remove the iPod Cache Folder, so I did and now I can't sync any pictures. What happens is that when I press "Syncronize" - it syncronizes - but no pictures added. The Camera Roll is fine - it's just when I try to add something from a folder. I've tried different folders, removed everything to do with iPod Cache Folder. The picture I'm trying to add is a .jpg. I installed iPhoto to see if that makes any difference - but no .. it's still the same. On my PC it works just fine, no problem what so ever. Syncronizing music on my mac to the iPhone works fine too. What's going on?
