Symbian OS
Symbian community
Espoo, Finland
Nokia became the major contributor to Symbian's code since it then possessed the development resources for both the Symbian OS core and the user interface. Since then Nokia maintained its own code repository for the platform development, regularly releasing its development to the public repository. Symbian was intended to be developed by a community-led by the Symbian Foundation, which was first announced in June 2008 and officially launched in April 2009.
