well, guys, 512 RAM was only in 100 prototypes tested AFAIK, with first UI made. as MeeGo changed to todays Harmattan with UI as we know it, it hat same specs + stereo speakers and 12MPx sensor with hardware key for camera. these were called "Beta2" (silver, with curved glass) and that was also used for that well known video that revealed us the phone. I held one, unfortunately I have only casual N950 in black even without a box.

that's all I know.
