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.
