Nokia today submitted a proposal to Symbian that would guide how the latter's late 2010 OS, Symbian^4, should look. The new OS layout is a refinement of an early tease and includes multiple home screens and widgets like Android, albeit as distinct pages rather than part of one continuous desktop.It would also have a much less cluttered interface with menu bars that can disappear and a primary menu that would involve just top-level items for apps, contacts, music and images.
