New Lion MacBook Air Address Book deletes all entries from MobileMe Contacts on sync Start with a new MacBook Air running Lion. Configure it's address book to synchronize with MobileMe.  The MobileMe contacts list has 374 items, synched from another Mac running Snow Leopard.

After invoking Sync on the MBA, all items are deleted from the MobileMe Contacts, and the MBA Address Book has just two entries: Apple, and the MBA user account.

This behavior is the same whether the user chooses Merge or Replace Data on This Machine.

The desired result is for the MBA to be updated with the 374 items in MobileMe.

Any suggestions?
I have a similar issue here, but not involving MobileMe.
I
've been struggling to see any of my iPhone 4 (running iOS 5 beta4) contacts appear in Lion's Address Book. It's all empty, whatever I do through iTunes (10.5 beta 4) (either manual syncing of Contacts, or by using iCloud). 

At least all my contacts are still on the iPhone...  but i'm stuck with a beautiful new Address Book on Lion which has 0 contacts... (or just that "Apple Inc" and "Me" contact cards)..
