BlackBerry OS - definition
BlackBerry OS is a proprietary mobile operating system developed by Research In Motion (RIM) for its BlackBerry line of smartphones.
The BlackBerry platform is perhaps best known for its native support for the corporate communication environment, which allows complete wireless activation and synchronization of email, calendar, tasks, notes, and contacts.
Currently deployed versions include the BlackBerry Device Software v5.0, the BlackBerry 6 OS, and the BlackBerry 7 OS.
BlackBerry 10 OS is a QNX-based operating system, similar to the one found on RIMís Playbook tablet. It will replace the BlackBerry OS on smartphones and tablets in 2013. Details are yet to be disclosed.
