Symbian is Open Source, so What?

Nokia - at last -  released the Symbian OS3.0 source code for all phone manufacturers after two years from acquiring Symbian. The director of the Symbian Foundation, claims that the new, open Symbian has an advantage over Android as Symbian is fully open, he says, while “about a third of the Android code base is open and nothing more. And what is open is a collection of middleware. Everything else is closed or proprietary.”
Though the public availability of the source code, it seems that there is no much interest for the newly opened OS. Symbian is facing very aggressive competition with Android and iPhone. Even Nokia is competing herself with the Maemo operating system that is used in the N900 phone. Also the very low penetration rate for Nokia in United States make Nokia's situation the worst.

Can Nokia keep its current position in the phone market? Who knows?
