Hi. In preparation for iOS4, I just downloaded iTunes 9.2. However, when I attempted to backup/sync my iPhone, I receive the following error message; The iPhone "XXXXXXXX" cannot be synced. An unknown error occurred (13019). I restarted both iTunes and my PC, but still no luck. Does anyone know what this means and what I can do to resolve it? Thanks! EDIT: Figured it out. ALL SET.
