Negri Electronics and TechnoBuffalo call it Nokia N9. Those who claim to know better, however, say it's either Nokia N8-01 or Nokia E7.
I say whatever the real name is, leaked Nokia slider looks nothing short of great.
Note that C0-00 was also the prototype name of recently announced Nokia N8.

While our sources failed to provide confirmed specifications, it seems that Symbian^3 Operating System, 3.5" screen with 360 x 640 pixels resolution, Wi-Fi, GPS and 3G with HSDPA connectivity options are almost a sure bet.
