Hey guys, This is actually for my iPod Touch (4th Generation on iOS5), but I figured since Contact Sync issue is more common amongst iPhone users, I should ask here. iPod Touch (4th Generation, iOS 5.0.1) Mid-2010 Macbook Pro (Lion 10.7.3) Anyway, I've sync'd my contacts to my iPod Touch before. I was editing the contacts on my MBP by adding new contacts, new numbers/emails, adding pictures, etc. However, when I sync the contacts in iTunes, none of the changes are reflected on my iPod Touch. Things to keep in mind: I tried flicking Contacts in the iCloud settings on and off (on both the computer and the iPod settings), syncing with iTunes on and off I went to iTunes and checked off "Replace information on this iPod" under Contacts Sync'd with "Sync Address Book Contacts" both on and off I have iCloud enabled on the Address Book on my MBP I do NOT have my address book set up to sync with Google and Yahoo messenger The contacts already on my iPod were from contacts I had on my computer already. I never sync'd my MBP with other address books It seems to simply ADD contacts/duplicates to both my iPod and my Mac's address books, but not sync them together Anyone with any suggestions for what I can do? Is there a way I can just delete all the contacts on my iPod Touch? I'm trying to figure this out because I plan on getting an iPhone 4S in the future, and I want to know if this sync'ing isn't going to be an issue.
