I have a user with a new Blackberry. The address book he uses (specifically created to sync with the BB) has become cluttered with duplicates when he makes changes on the device (although it was set to "server wins"). I disabled wireless sync, cleared the book from the device manager, cleaned up the book on the server, disconnected from the computer, enabled wireless sync, and somehow, all of the duplicates are back.

Can anyone tell me how else this can be done? I've been trying for a few days, and he's getting a little cranky about the four hour wait, only to have the same mess reinstated.
