BlackBerry OS

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.

BlackBerry OS provides multitasking and supports specialized input devices that have been adopted by BlackBerry for use in its handhelds, particularly the trackwheel, trackball, and most recently, the trackpad and touchscreen.

The BlackBerry platform natively supports corporate email, through Java Micro Edition MIDP 1.0 and, more recently, a subset of MIDP 2.0, which allows complete wireless activation and synchronization with Microsoft Exchange, Lotus Domino, or Novell GroupWise email, calendar, tasks, notes and contacts, when used with BlackBerry Enterprise Server. The operating system also supports WAP 1.2.

Updates to the operating system may be automatically available from wireless carriers that support the BlackBerry over the air software loading (OTASL) service.

Third-party developers can write software using the available BlackBerry API classes, although applications that make use of certain functionality must be digitally signed.

Research from June 2011, indicated that approximately 45% of mobile developers were using the platform at the time of publication.

BlackBerry OS was discontinued after the release of BlackBerry 10 in January 2013, however support for the older OS continued until the end of 2013.
