Overview• History

… 1998 - Symbian was formed by Psion, Nokia, Ericsson and Motorola.

… First Symbian phone was released in 2000

• Ericsson R380

… 2.5G phone released early 2002

• Nokia 7650

… 3G phone released in December 2002

• 3G FOMA F2051 from Fujitsu

… EKA2 was announced in 2004

… Security Platform was introduced in 2005 on v9


Overview (continued)• Development Languages

… C++

… Java

… Flash Lite

… Python, Ruby

… OPL

… PIPS


Overview (continued)• Symbian C++

… Leaves

… Cleanup

… Descriptors

… Active Object


Overview (continued)• Versions

… v6.0, v6.1,v7.0, v7.0s, v8.0, v8.1a, v8.1b, v9.1…v9.5

• True Micro-Kernel… User Mode & Kernel Mode

… Only a minimal parts of system runs as kernel mode

… Real-Time OS


• Features… GUI

… Telephony

… Multimedia

… Messaging

… Networking

… Short link (USB, Bluetooth, IR)

… Security
