It has taken nearly two years for the promise to be realised, but the Symbian Foundation has finally brought the most popular smartphone platform on the planet out of the constraints of licensing, making it an open source project for the first time.
What the foundation claims to be billions of dollars' worth of coding will be made available to anyone who wants it, meaning private organisations and individuals will be able to get their hands on the basic programming that binds the Symbian world together.
Symbian Foundation spokesperson Lee Williams told the BBC News website: "This is the largest open source migration effort ever.
"It will increase rate of evolution and increase the rate of innovation of the platform."
Symbian has been struggling to evolve as a platform ever since the launch of the iPhone and Google's Android changed the way in which most firms approached software creation for mobile phones.
The Symbian Foundation is formed of a number of major manufacturers, including Nokia, LG and Motorola, and until now it was only these member firms that were allowed unlimited access to the Symbian source code.
Symbian has now been around for a decade and its guardians are looking to the wider community to help catalyse future evolutions and improvements for the platform.
Although Nokia owns Symbian and is by far the most dominant producer of Symbian-based products, its involvement in the creation of new versions is set to drop below 50 per cent by 2011, now that the platform has gone open source.
