I have been happy using MobileMe to sync my iPhone with my MacbookPro but synchronization of the Macbook Address Book with MobileMe stopped about a month or two ago. I have tried various fixes but have not been successful. Even visited the Apple Store in Sydney where a helpful assistant proved that Contacts on the iPhone still synced with MobileMe. Calendar etc still sync but not Contacts, so it is not a password or account problem. Each time I open Address Book preferences, it shows 'Sync with MobileMe' not ticked. I tick it, press Sync and it goes through the motions, but MobileMe has not changed when I check later. Have even reset. Again, the system seems to go through the motions but I find the iPhone Contacts are restored even when my iPhone is not connected. Can anyone suggest a fix? Thanks.
