BlackBerry OS is a proprietary mobile operating system developed for BlackBerry line of smartphone handheld devices. The operating system provides multitasking and supports specialized input devices that have been adopted by BlackBerry for use in its handhelds.
The BlackBerry platform is perhaps best known for its native support for 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.
