ecommerce. An application can access other directories marked as open but cannot access another application’s private directory.

•Additional platform security includes full encryption and certificate management, secure protocols (HTTPS, SSL and TLS) and WIM framework.

EKA2 Kernel

•A new realtime kernel (EKA2) with guaranteed response times provides the basis for a robust and power-efficient phone. Predictable real time operation means that the OS will respond to interrupts, system and user threads within a known period. This means that no task in the system can prevent the OS from responding to key tasks.

•Support for multiple simultaneous IP connec- tions.

Development and testing

•Provides new customization and configurability options for the operating system.

•Symbian OS is built using the ARM RVCT 2.1 compiler. This compiler is compliant with the ARM EABI standard. This allows compatibility with the latest ARM compilers and reduces the Symbian OS footprint while enchancing perfor- mance.

•Developing for Symbian OS - native system and application development in C++, supported by CodeWarrior and shortly Eclipse-based IDEs (. Java MIDP 2 supported by all mainstream Java tools. PC-hosted emulator for general develop- ment.

UIQ 3.0

The new UIQ 3.0 platform offers support for multiple form factors on the same code base and ease of operator configuration.

UIQ 3.0 is based on Symbian OS v9.1 and is equipped to meet the various demands from phone manufacturers, network operators and end users.

•Developers can utilize the new features of UIQ 3.0 to easily develop applications.

•The SDK (Software Developers Kit) can be used to expand these applications or create new ones. Building blocks, layout managers and a wide range of controls, such as menus and dia- logs, make it easier to design applications for UIQ. Using these tools also gives the applica- tions the UIQ look and feel which users are familiar with. The application framework and system services are the basis of the UI platform.
