The iPhone [name] could not be synced because the sync session failed to start

I started seeing this error after "upgrading" to iOS7.  There were lots of suggestions on the Net but this is the one that worked for me:

• Close iTunes and disconnect all iOS devices
• Open Terminal
• Go to /var/db/lockdown
• rm * (remove the contents of the folder, not the folder itself)
• Relaunch iTunes and reconnect your iOS device
