We just read over on Inside BlackBerry that the BlackBerry PlayBook has been updated to BlackBerry Tablet OS v1.0.7.3312.  This update address the Adobe Flash Player issue noted by Adobe last month in in Adobe Security Bulletin APSB-11-26.

This update to the BlackBerry PlayBook is not Tablet OS 2.0 which we should get a preview of later this month at BlackBerry DevCon.
