Nokia's popular mobile operating system, "Symbian," is now open sourced. In a blog post, Nokia announced that it's "making the latest version of the Symbian platform's source code available to our platform development partners" and that the Symbian Foundation has been replaced by "an open and direct model from Nokia."
"As we announced earlier, Nokia will "no longer refer to official releases as Symbian ^3 or Symbian^4," but will deliver continuous evolution of the platform to partners and customers -- including consumers. In line with this approach we're not delivering software builds, but do offer build tools through this website, and a SDK through Forum Nokia," Nokia said.
Symbian was originally created by British company Symbian Ltd and bought by Nokia in 2008 for €264 million, at the time of purchase its major share holders consisted of Nokia, Ericsson, Sony Ericsson, Matsushita and Samsung.
Nokia also mentioned about their partnership with Microsoft, and said that they plan Windows Phone 7 as the their primary smartphone strategy. Nokia plans to ship at least 150 million Symbian smartphones and to continue deliver innovation and software updates to the platform.
"To achieve all of this, we need the collaboration with our platform development partners and continue to value an open way of working."
