Back in 2008, Nokia increased its 48% share in Symbian to 100% – and said it planned to transform the company into an open software platform for mobile phones. That led to the creation of the non-profit Symbian Foundation, which allowed its members to use its mobile platform under a royalty-free licence.
Today the Symbian Foundation says it's completed the open source release of its source code. The Symbian platform, which has shipped on more than 330 million devices, making it the world’s most widely-used smartphone platform, is now completely open. This move has been completed four months ahead of schedule.
