First we had an odd leak of an OS for the PlayBook and now we have an official release. BlackBerry has pushed out OS 184.108.40.2063 as an official OS release for the device. This update packs in 390MB+ so its a whopper. On the other hand it includes an updated Adobe Flash for security along with other “Tweaks & Bug Fixes” from what we hear. So hit that check for updates button and let us know what you find!
