Apparently I'm the only person that had this problem, but in case you are among the unfortunate few who got a pre-release of 5.0.0.484 through the desktop manager and are having issues with various apps (e.g. voice dialing) not functioning,
there is a fix.
Sprint is claiming the official release is not out yet and their only advice is for you to roll-back to a previous version, 4.7.x.x, presumably.
HOWEVER
If you download and install the 5.0.0.801 build from
http://tinyurl.com/yhch4b7
when you open the Desktop Manager you will see two versions of 5.0.0 on your DM, "5.0.0" and "5.0.0 for 9630"
Since your Desktop Manager can't tell the difference between development stages of builds (the 4th integer in the version naming sequence, like "x.x.x.801") Desktop Manager will tell you your smartphone is up to date.
1) Roll-back to 4.7.x.x
2) Immediately upgrade to "5.0.0 for 9630"
3) Run/upgrade 3rd party apps as necessary to get updates.
4) Enjoy a working official build of 5.0
