Nokia are no strangers to split-QWERTY keyboards, but while the old E70 went with a flip design, this mockup of what's tipped to be the Nokia C2 has a more unusual rotating display. According to information obtained by Ciao Mondo, the C2's screen section flips to the side to reveal the second half of the keyboard; still, this would be an entry-level device so we probably shouldn't expect anything too dramatic when it comes to functionality.
The only other specifications tipped are a 2-megapixel camera with Carl Zeiss optics and a 240 x 320 display. No word on whether that display is a touchscreen, but given the "C" series of handsets is positioned as a lower-end range, we doubt it.
Of course this could all be fake, but with the recent proliferation of QWERTY phones from Nokia the company do seem to be putting some emphasis on mobile messaging. No word on when the C2 might launch.
