Symbian is a mobile operating System (OS) targeted at mobile phones that offers a high-level of integration with communication and personal information management (PIM) functionality. Symbian OS is designed for the mobile phone environment. It started life as the operating system for the Psion series of consumer PDA products (including Series 5mx, Revo and netBook), and various adaptations by Diamond, Oregon Scientific and Ericsson. The first dedicated mobile phone incorporating Symbian OS was the Ericsson R380 Smartphone, which incorporated a flip-open keypad to reveal a touch screen display and several connected applications. Most recently available is the Nokia 9210 Communicator, a mobile phone that has a keyboard and color display, and is fully open to third-party applications written in Java or C++.
