Research In Motion may be gearing up to launch the latest version of its BlackBerry PlayBook operating system in just a few short days. Engadget learned on Friday from an anonymous source that RIM will launch BlackBerry PlayBook OS 2.0 on Tuesday, February 21st. This is a date that we’ve already heard before, but the new screen shots seem to solidify those early rumors. RIM has said that BlackBerry PlayBook OS 2.0 is part of how it plans to “get 4G right,” so maybe we’ll even see some new hardware after it’s been official. The operating system update will also allow IT administrators to control other BlackBerry devices all from one easy interface, and the leaked images say added support for managing Android and iOS devices will land in March. TechnoBuffalo will be sure to keep you up to date when the new OS, which is expected to be about 400MB in size, hits our devices.
