The version of iTunes that comes with beta 4 cannot sync devices that have the beta 2 software installed. To avoid this problem, do the following:
1. Sync any devices that have beta 3 installed to the version of iTunes that came with beta 4.
2. Upgrade iTunes to the version that comes with beta 4.
3. Connect the device and install the beta 4 software. (Understand that you might see a failure to sync error when you first connect the device.)
4. After installing the beta 4 software, restore from your the backup you made in step 1.
