While trying to update an Address Book entry (in my BlackBerry), I got the "Address updated externally. Changes will be lost and the viewer closed." message (in my BlackBerry).

While trying to sync, Desktop Manager showed the "Error Encountered 0x80040FB3, Check Documentation" message (and the sync failed).

When I fixed the problem in my BlackBerry device (by pulling out the battery), the sync started to work.

The KB14818 Doc (in the BlackBerry Technical Solution Center) should be updated to contemplate this.
