The Symbian Foundation said the Symbian platform is now completely open and the source code is available for free.
The move has been completed four months ahead of schedule and provides the basis for unlimited mobile development based on innovation and openness.
Any individual or organization can now take, use and modify the code for any purpose, whether that be for a mobile device or for something else entirely.
Also available for download are the complete development kits for creating applications (the Symbian Developer Kit) and mobile devices (the Product Development Kit).
