My iPhone 4 and iPad sync with each other through my old MacBookPro which runs Snow Leopard, (but cannot run Lion). Apparently OSX Address Book is not stored in the same place as the latest release of IOS Contacts or iTunes. My old iPhone 3 still syncs properly. Cannot move to iCloud because of old MBP.
What to do to re-enable sync?
