The key benefit of EPOC32 over its 16bit predecessor is the ability to multi-task, perform multiple functions at once. In newer devices, this might mean being able to surf the web using the phone and not lose your content when answering an incoming call.

Symbian OS is an open source operating system for mobile phones primarily used on Nokia advanced or data enabled smart phones. Symbian OS runs exclusively on ARM processors and has evolved from Psion’s EPOC which was developed as a basic operating system for early electronic organizers. The Psion EPOC OS was refered to EPOC16 beginning in the late 1990′s to help differentiate it from the newer 32bit Operating system EPOC32, which eventually became Symbian OS. Psion software created a joint venture with several mobile hardware manufacturers, Ericsson®, Motorola®, and Nokia® called Symbian and eventually took on the name Symbian Software, renaming EPOC32 Symbian OS.

Many third party manufacturers were able to license the 32bit EPOC OS for their organizers and other mobile data devices. Since the late 1990′s,Symbian OS has become one of the most popular mobile device operating systems available.

Symbian OS has also modified to include soft features such as global positioning software (GPS) which will become as common as a camera in the very near future. Service providers and other companies could then publish location based services that interact with the GPS found in a mobile phone, appearing on the display once the user is near an application.
