RIM is also launching a closed beta program with selected enterprise customers to test its security enhancements, which include allowing IT to manage PlayBook tablets with RIM's extra-cost BlackBerry Enterprise Server (BES) server software. The original PlayBook lacked such security unless it was wirelessly tethered to a BlackBerry smartphone, which was its only means of accessing corporate email, contacts, and calendars. PlayBook OS 2.0 is expected to remove the tethering requirement of the original PlayBook's BlackBerry Tablet OS 1.0. (PlayBook OS is the new name for that operating system.)
The PlayBook OS is based on the QNX operating system that RIM bought in spring 2010 to be the basis for its tablets and, sometime in the 2012-13 timeframe, the basis for a new operating system for its BlackBerry smartphones. Last week, RIM said it will provide a unified tablet/smartphone operating system called BBX, based on the QNX/PlayBook platform. It said that applications developed for the PlayBook OS would be compatible with BBX, but did not make the same promise for BlackBerry OS apps.
RIM's plan is to release PlayBook OS 2.0 for its tablets, then later release BBX for both PlayBook tablets and BlackBerry smartphones, though it gave no specific timeline. It also has not said whether any current BlackBerry smartphones will run the BBX operating system when it becomes available.
RIM's previous promises of future compatibility have not always been honored. In July 2010, RIM announced that its then-imminent BlackBerry OS 6.0 would run on then-current BlackBerrys, but it later changed its plans, restricting BlackBerry OS 6.0 to devices released in fall 2010 and winter 2011. In September 2011, it released BlackBerry OS 7.0, which had been previously named BlackBerry OS 6.1, and said it would run only on new BlackBerry models released in fall 2011 and later.
