My sync is going wrong somewhere along the line and creating duplicate lists of some contacts to build up. I deleted them all yesterday afternoon and now have about 20 or so of some contacts. Some do not duplicate at all. I found this thread over at apple http://discussions.apple.com/thread.jspa?threadID=2138659&start=0&tstart=0 but as my mobile me account contains the duplicates as well cant get the workaround (deleting address book file) to work. Any one here having similar problems?
