When I upgraded my old 1st generation iPhone to OS 3.0, I made the mistake of telling iTunes to sync all my contacts with information on my Mac, overlooking where it said that it was currently being synced via MobileMe (as I have a MobileMe account). I now have an iPhone 3G and the problem persists. I can't, for the life of me, figure out how to stop this. I have unchecked the appropriate boxes in iTunes, but all of my contact information is still duplicated. I will attach two screen shots to show what is currently showing up on my iPhone. I have already tried a restore, which does nothing to correct this problem. Any help is resolving this will be greatly appreciated.
