The Symbian Foundation today unveiled the Symbian^3 (S^3) platform, the first entirely open source Symbian release. S^3 is expected to be “feature complete” by the end of Q1 and the release will include: significant usability and interface advances, faster networking, acceleration for 2D and 3D graphics in games and applications, HDMI support (High-Definition Multimedia Interface), music store integration, an improved user interface with easier navigation and multi-touch gesture support, a feature-rich homescreen, and the ability to run even more applications simultaneously.

The Qt toolkit is pre-integrated into all kits and the runtime in S^3 will run on existing devices back to S60 3.1. The Web Runtime support provided in the platform remains a key part of the developer story, allowing web developers to directly re-use their skills in HTML, CSS, Javascript and AJAX to create homescreen widgets and standalone applications.

Lee M. Williams, Executive Director of the Symbian Foundation, said: “S^3 is another huge milestone in the evolution of our platform. Now that it is fully open source, the door is open to individual contributors, device creators and third-party developer companies, as well as other organizations, to create more compelling products and services than ever before. We have enjoyed significant momentum since we completed S^2, with companies including Sun, Nokia, Ixonos, Comarch and Accenture, among others, contributing to S^3. We are now looking to build on this momentum and remain on course to complete S^4 later this year.”
