New contacts added to iPhone do not sync over to Address Book

New contacts added to my iPhone do not sync over to my Address Book. This happens intermittently, but frequently. Consistently, I gradually build up a list of contacts that only exist on my iPhone and which simply will not sync to my Address Book. So far, every time I discover this, I waste time identifying the specific contacts that are not transferring, and I hand enter them into my computer's Address Book, and then delete them from the phone, and then sync to get them to go back on the phone.

MacBook Pro, Mac OS X (10.6.2), iPhone 3G

Okay, I tried this:
1. Backup Address Book data.
2. Delete all entries.
3. Shut down Address Book.
4. Restart Address Book.
5. Import the backup.
6. Shut down and restart Address Book.
7. Use iTunes to sync to my iPhone again.
8. Shut down and restart Address Book again.

Nope. Two of my contacts still did not transfer from my iPhone to my Address Book. Past history says that number will continue to grow over time.

The address book database on your Mac may have some corruption.

Try the following.

With the Address Book quit, go to Home > Library > Application Support > AddressBook. Delete all contents within the AddressBook folder, but don't empty the Trash on your Mac in case you need to restore the contents back within the AddressBook folder.

Import the Address Book archive that was previously exported.

Test if this resolves it.

Okay, that failed too.
The two contacts I added to my iPhone since last time I manually added them to the Address Book, and deleted them on my iPhone, and sync'ed, are still not sync'ing.
I really think that if you Google this issue, and read some of the reports, it sounds like many other folks are having this issue but are either not describing it repeatedly until it is crystal clear or are giving up and resolving it manually.
It would be nice to see the issue resolved as the bug it appears to be.

I have "All Contacts" and then I have "From My Mac"/"All from My Mac"


"All Contacts" is normal when syncing contacts direct with the Address Book via the iTunes sync process.

"From My Mac"/All from My Mac" is available when accessing a MobileMe account on an iPhone and syncing contacts over the air along with syncing contacts direct with the Address Book via the iTunes sync process, which is not necessary and will cause duplicate contacts on the iPhone.

Do you have a MobileMe account?
