Nokia Phones Operating system (OS)

Originally Nokia phones had a custom Nokia OS operating system developed specifically for Nokia mobile phones.

The first Nseries device, the N90, utilized the older Symbian OS 8.1 mobile operating system, as did the N70. Subsequently Nokia switched to using SymbianOS 9 for all later Nseries devices (except the N72, which was based on the N70). Newer Nseries devices incorporate newer revisions of SymbianOS 9 that include Feature Packs. The N800, N810 and N900 are as of July 2010 the only Nseries devices to not use

Symbian OS. They use the Linux-based Maemo.

Nokia stated that Maemo would be developed alongside Symbian. Maemo has since (Maemo "6" and beyond) merged with Intel's Moblin, and become MeeGo, which will continue to be developed for mobile devices

The Nokia N8 is the first device to function on the Symbian^3 mobile operating system.

Nokia revealed that the N8 will be the last device in its flagship N-series devices to ship with Symbian OS.

Instead, Nokia will use Microsoft Windows Phone for its high-end flagship devices, and revealed the Nokia N9 will function on the MeeGo mobile operating system.

On February 11, 2011, Nokia announced that it would migrate from Symbian to Windows Phone 7. Nokia CEO Stephen Elop announced Nokia's first Windows phones at Nokia World 2011: the Lumia 800 and Lumia 710. These phones were launched on November 14, 2011.

On June 22, 2011 Nokia made an agreement with Accenture as an outsourcing program. Accenture will provide Symbian-based software development and support services to Nokia through 2016 and about 2,800 Nokia employees will be Accenture employees at early October 2011. The transfer was completed on September 30, 2011.
