iPhone4, iPad2, MacBook and MobileMe all syncing together here via MobileMe of course. I've noticed that I have dual entries for some contacts now. Think it started when I started syncing MobileMe in addition to regular iTunes syncing. Yesterday I deleted my MobileMe account on my iPhone to see if the dupes would go away and they did. Problem is I ended up with a bunch of raw phone numbers in the MMS and Phone app windows since the contact names got erased. Fine, I went back in and added MobileMe again and all the contact names came back. Luckily everything is safe with these backups but I want to consolidate the contacts from my iPhone and MobileMe and delete MobileMe or not sync with iTunes. Which should I do? Quit MobileMe syncing or not sync with iTunes anymore? With iOS 5 will all this be automatically taken care of?
