i installed latest version of i tunes and since then i cant sync my i phone any more. A dialog box is coming with a title 'adding file' and inside the box the following message is shown, 'processing: 20100725 193403.m4a'. i tried it on another pc and the same message popped up. whether its worth mentioning or not, i installed the new version of i tunes on 2010/07/25. i am using i phone 3G. any help please?
