The iPhone "..." could not be synced because the sync session failed to start

I am trying to sync my iPhone 4 with iTunes and I receive this "The iPhone 'XYZ's iPhone' could not be synced because the sync session failed to start." I have synced this phone many times in the past without any issues and this error just started to occur. I have done all the usual: reset my phone settings, restarted my computer etc. Does anyone have any suggestion as to what I could do?

iPhone 4, Mac OS X (10.6.7), Mac OS X (10.6.8)

iTunes

The version of iTunes that comes with beta 2 cannot sync devices that have the beta 1 software installed. To avoid this problem, do the following:

  1. Sync any devices that have beta 1 installed to the version of iTunes that came with beta 1.
  2. Upgrade iTunes to the version that comes with beta 2.
  3. Connect the device and install the beta 2 software. (Understand that you might see a failure to sync error when you first connect the device.)
  4. After installing the beta 2 software, restore from your the backup you made in step 1.
