Symbian is a mobile operating system (OS) and computing platform designed for smartphones and currently maintained by Accenture.The Symbian platform is the successor to Symbian OS and Nokia Series 60; unlike Symbian OS, which needed an additional user interface system, Symbian includes a user interface component based on S60 5th Edition. 
Symbian OS was originally developed by Symbian Ltd. It is a descendant of Psion's EPOC and runs exclusively on ARM processors, although an unreleased x86 port existed.

Symbian^1 is the first release of the touch optimized version of Symbian OS. It incorporates Symbian OS and S60 5th Edition (which is built on Symbian OS 9.4) and thus it was not made available in open source.

The Nokia 5800 XpressMusic is the first device to feature Symbian^1 followed by the Nokia N97 which became the first in the N-Series running Symbian touch based OS.
