Nokia, Sony Ericsson, Motorola and NTT DOCOMO announced today their intent to unite Symbian OS, S60, UIQ and MOAPto create one open mobile software platform.

Together with AT&T, LG Electronics, Samsung Electronics, STMicroelectronics, Texas Instruments and Vodafone they plan to establish the Symbian Foundation "to extend the appeal of this unified software platform." Membership of this non-profit Foundation will be open to all organizations. This initiative is supported by current shareholders and management of Symbian Limited.

Symbian's software is used in two-thirds of smartphones -- handsets with computer-like capabilities -- and 6 percent of all cellphones, but new platforms such as Google's Android and Apple's iPhone could challenge its dominance.

To enable the Foundation, Nokia today announced plans to acquire the remaining shares of Symbian Limited that Nokia does not already own and then contribute the Symbian and S60 software to the Foundation. Sony Ericsson and Motorola today announced their intention to contribute technology from UIQ and DOCOMO has also indicated its willingness to contribute its MOAP(S) assets. From these contributions, the Foundation will provide a unified platform with common UI framework. A full platform will be available for all Foundation members under a royalty-free license, from the Foundation's first day of operations.

The Foundation will make selected components available as open source at launch and then work to establish a complete mobile software offering available in open source. This will be made available over the next two years and is intended to be released under Eclipse Public License (EPL) 1.0.

"Ten years ago, Symbian was established by far sighted players to offer an advanced open operating system and software skills to the whole mobile industry", said Nigel Clifford, CEO of Symbian. "Our vision is to become the most widely used software platform on the planet and indeed today Symbian OS leads its market by any measure. Today's announcement is a bold new step to achieve that vision by embracing a complete and proven platform, offered in an open way, designed to stimulate innovation which is at the heart of everything we do."

"Establishing the Foundation is one of the biggest contributions to an open community ever made," said Olli-Pekka Kallasvuo, CEO of Nokia. "Nokia is a strong supporter of open platforms and technologies as they give the freedom to build, maintain and evolve applications and services across device segments and offer by far the largest ecosystem, enabling rapid innovation. Today's announcement is a major milestone in our devices software strategy."

The Foundation is expected to start operating during the first half of 2009, subject to the closing of the acquisition of Symbian Ltd by Nokia.

Symbian OS is a proprietary operating system, designed for mobile devices, with associated libraries, user interface frameworks and reference implementations of common tools, produced by Symbian Ltd. It is a descendant of Psion's EPOC and runs exclusively on ARM processors.

On June 24, 1998, Symbian Ltd. was formed as a partnership between Ericsson, Nokia, Motorola and Psion, to exploit the convergence between PDAs and mobile phones.
