RIM recently confirmed that its PlayBook tablet would receive its new 2.0 operating system upgrade in "February," but now there may be a date and time. According to documents obtained by Engadget, PlayBook owners will be able to download the update over-the-air starting at 4:01AM on Tuesday, February 21st — well before RIM's self-imposed deadline. We detailed the upgrade at CES in January, which will finally bring native email, contacts, and calendar apps to the tablet. Other improvements include upgrades to the keyboard and homescreen layouts, and the ability to use a BlackBerry device as a keyboard and mouse. Oh, and don't forget Android app support.

BlackBerry Mobile Fusion will also launch on Tuesday, enabling large organizations to manage fleets of PlayBook tablets and BlackBerry phones wirelessly. It will expand to include iOS and Android devices in March, allowing IT departments to provision employees' own devices. It had previously been speculated that the company would introduce the upgrade at Mobile World Congress which kicks off on February 27th, but early PlayBook announcements could pave the way for more BlackBerry 10-related news at the show instead.
