Symbian OS Version 9.3

Symbian OS is the advanced, open operating system licensed

by the worlds leading mobile phone manufacturers.

Designed for the specific requirements of advanced 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, including Nokia S60, UIQ and the NTT

DoCoMo common software platform for 3G FOMATM handsets.
