The software is indeed a beta version and has not been fully vetted by Sprint.
I am closing this thread and will open a new one when we have the official release.
I do not have all of the details yet, but there is a software update - version version 184.108.40.206 available for the Tour.
To download go to Options>Advanced options>Wireless Update
It has been reported to me that it takes about 30 minutes to complete the download.
I will update this post with a list of fixes once I get the official list, but can report that one person that downloaded sees improved trackball movement.
