While official support for Symbian may have been shut down, enthusiasts around the world are not giving up yet. Being an Open Source software, some enthusiasts have launched a petition for the source code and the latest development builds to be made publicly available so anyone who wants to work on it, improve it, or use it, can do so.
It is obvious that Microsoft is not predisposed to having Symbian still breathing and alive somewhere. Enthusiasts have been known to take a piece of software and start a revolution with it. Think of CyanogenMOD for Android. Still, I doubt that Symbian OS in the wild can ever be a serious threat to Windows Phone. I would love to see Symbian kept alive via enthusiast development. We could see one or two interesting things, no matter how small scale, come out of it.
So, yes; I signed the petition. If you are a Symbian OS fan and would love to do same, hit the link below.
