Today, the BlackBerry PlayBook silently received an update to Tablet OS version  While this is no BlackBerry 10, it is a good indication that RIM is still working to polish the tablet OS amid the recent focus on the  new upcoming platform.

The update brings with it improvements to the AIR and Flash runtimes, and perhaps some other minor fixes to the OS, all in a nice 37 MB package.  So if you haven’t mashed the “Check for updates” button already, I’ll leave you to it!

If you notice any other improvements, why not share them in the comments section below!
