  15. 15. License..<br />Symbian is not open source software yet. <br />Phone manufacturers and other partners are provided with parts of its source code. <br />The APIs are publicly documented and up to Symbian 8.1 anyone could develop software for Symbian OS.<br />Symbian9.1 introduced capabilities and Platform Security framework.<br />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.<br />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.<br />
  16. 16. Application Programming Languages..<br />The native language of the Symbian OS is C++, although it is not a standard implementation.<br />Other languages which can be used are,<br />OPL – Open Programming Language is an embedded programming language found on e.g. the Nokia 9200, 9300 and 9500 Communicator series mobile telephone/PDA <br />Python<br />Visual Basic<br />Simkin<br />Perl <br />together with the Java ME and PersonalJava flavours of Java.<br />
  17. 17. Usage Examples..<br />Ericsson R380 (2000) - first commercially available phone based on Symbian OS.<br />Nokia 9210 Communicator smartphone(2001), 9300 Communicator (2004), 9500 Communicator (2004) using the Nokia Series 80 interface.<br />UIQ interface<br />Used for PDAs such as Sony Ericsson P800 (2002), P900, G702(2008), Motorola A920<br />Nokia S60 (2002) interface<br />Nokia 7650, Nokia 3650 ….etc…<br />Nokia Series 90 interface<br />Nokia 7710<br />MOAP(S) interface<br />Fujitsu, Mitsubishi, Sony Ericsson and Sharp phones for NTT DoCoMo(Mobile Operator)in Japan<br />
