Nah, it ain't the update that'll bring a standalone email client to your BlackBerry PlayBook, but at least it's some positive news in an otherwise gloomy arena surrounding RIM. Version 1.0.6 of the BlackBerry Tablet OS was just cut loose today, bringing support for Adobe's Flash 10.3 and AIR 2.7 software. In other words, users should see improved Flash performance, and they'll also be able to tap into a new array of apps crafted with AIR 2.7. Oh, and for the security mavens? There's a few built-in updates to safeguard you and yours. It's available over-the-air right now, and if you don't see an update just yet, be patient -- it's en route, we swear.
