Symbian OS operating system
Symbian OS is the open operating system licensed 
by the world's leading mobile phone 
manufacturers. It is designed for the specific 
requirements of advanced 2G, 2.5G and 3G mobile 
phones. Symbian OS combines the power of an 
integrated applications environment with mobile 
telephony, bringing advanced data services to the 
mass market.
Symbian OS supports a wide range of device 
categories with several user interfaces, this 
includes UIQ, which is the software platform used 
by Sony Ericsson P1.
Key features of Symbian OS v9.1
General
• Improved system performance, especially at 
start up.
• New multimedia framework supporting record-
ing, playback and streaming.
• Direct access to screen and keyboard gives 
high performance, graphics accelerator API, 
and increased UI flexibility (support for multiple 
simultaneous display, multiple display sizes and 
multiple display orientation).
• Java™ support for the latest wireless Java stan-
dards. See “Java™” on page 55 for more infor-
mation.
• Communications protocols using wide area net-
working stacks, including TCP/IP (dual mode 
IPv4/v6) and IPSec. Improved personal area 
networking support including infrared (IrDA), 
Bluetooth™ connectivity and the introduction of 
USB. Support is also provided for multihoming 
and link layer Quality-of-Service (QoS) on GPRS 
and UMTS networks.
• Symbian OS v9.1 is ready for the 3G market 
with support for: WCDMA (3GPP R4), GSM cir-
cuit switched voice and data (CSD), packet-
based data (GPRS), SIM, and U-SIM.
• Supports the Unicode Standard version 3.0.
• Data synchronization has been improved to 
cover the following: over-the-air (OTA) synchro-
nization support using OMA standards (OMADS 
1.2); PC-based synchronization over, Bluetooth 
connectivity, infrared and USB; a PC Connectiv-
ity suite providing the ability to transfer files and 
synchronize PIM data.
• Improved device management which provides 
network operators and enterprises with new 
capabilities to manage phones in the field. This 
includes OMA DM 1.1.2 support and OMA client 
provisioning 1.1.
• Support for Bluetooth wireless technology 
eSCO and Bluetooth stereo headset profiles 
have been implemented.
Security
The aims of the security developments in Symbian 
OS v9.1 are to protect the integrity of the phone, 
provide extra control over user billable events and 
to prevent malicious software corrupting 
executables and data. The aims have been met by:
• Providing platform security by a proactive sys-
tem defence mechanism based on granting and 
monitoring application capabilities through 
Symbian Signed certification. The infrastructure 
allows applications to have private protected 
data stores. 
• A proactive defence mechanism against mal-
ware. The platform security infrastructure uses a 
capability based model which ensures that sen-
sitive operations, such as, modifying user data, 
making calls and using network connections, 
can only be accessed by applications which 
have been certified by an appropriate signing 
authority.
• Data caging, which allows applications to have 
their own private data protection. This allows 
applications a guaranteed secure data source. 
This can be used for applications, such as,
