    • What is Symbian OS??
      Symbian OS is the market leading open operating system for advanced data-enabled mobile phones licensed by the world’s leading mobile phone manufacturers. It is designed for the specific requirements of advanced 3G mobile phones and beyond.
      Microkernel based, 32-bit, pre-emptive multi-tasking
      Specialised for mobile
      Resource constrained devices (power, memory, wireless)
      ARM CPUs including ARMv6
      Secure
      Native platform security from v9 – PlatSec
      Capability model implemented here – involves Symbian Signed and manufacturer approval sometimes.
    • What is Symbian OS??
      OO “from the ground up”
      C++ implementation
      Pervasive use of OO idioms
      Statistics published February 2007 showed that ,
      Symbian OS had a 67% share of the smart mobile device market, with Microsoft having 13% (through Windows CE and Windows Mobile) and RIM (Research In Motion Ltd) having 10%

    • License..
      Symbian is not open source software yet.
      Phone manufacturers and other partners are provided with parts of its source code.
      The APIs are publicly documented and up to Symbian 8.1 anyone could develop software for Symbian OS.
      Symbian9.1 introduced capabilities and Platform Security framework.
      To access certain capabilities, the developer has to digitally sign their application. Have to sign via the Symbian Signed program; which uses independent Test Houses and/or phone manufacturer approval.
      In 2008 Nokia has stated that Symbian OS (including the platforms S60, UIQ and MOAP(S)) will become open source in the first half of 2009.
    • Application Programming Languages..
      The native language of the Symbian OS is C++, although it is not a standard implementation.
      Other languages which can be used are,
      OPL – Open Programming Language is an embedded programming language found on e.g. the Nokia 9200, 9300 and 9500 Communicator series mobile telephone/PDA
      Python
      Visual Basic
      Simkin
      Perl
      together with the Java ME and PersonalJava flavours of Java.
    • Usage Examples..
      Ericsson R380 (2000) - first commercially available phone based on Symbian OS.
      Nokia 9210 Communicator smartphone(2001), 9300 Communicator (2004), 9500 Communicator (2004) using the Nokia Series 80 interface.
      UIQ interface
      Used for PDAs such as Sony Ericsson P800 (2002), P900, G702(2008), Motorola A920
      Nokia S60 (2002) interface
      Nokia 7650, Nokia 3650 ….etc…
      Nokia Series 90 interface
      Nokia 7710
      MOAP(S) interface
