Tricks and Codes for Symbian based Nokia Mobile Phone

There are some new technology related open operating system called Symbian based OS. The main features are as;

Symbian OS was built to follow three design rules: the integrity and security of user data is paramount, user time must not be wasted, and all resources are scarce. This led to the writing of a microkernel, a request-and-callback approach to services, the concept of separation between UI and Engine (the business logic of a Symbian application). The OS is optimised for low-power battery-based devices and for ROM-based systems (e.g. features like XIP and re-entrancy in shared libraries). Applications, and the OS, follow an object-oriented design.

Symbian is not open source software yet. However, 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.

The common series of Nokia for this kind of OS are
