I’ll go ahead and say it: the fact that this unnamed, mostly undetailed Sony Ericsson touchscreen/QWERTY handset is running Symbian S60 5th Edition rather than Android is a travesty.
We only know that it’s running 5th Edition because of the one leaked shot you see above — and outside of that, we dont know a whole lot. It’s obviously packin’ a touchscreen above a fairly monstrous QWERTY keyboard. As GSM Arena points out, this looks a whole lot like a previously leaked Sony Ericsson handset called the Kurara, which didn’t have a keyboard. What the Kurara does have, however, is an 8 megapixel camera and 600Mhz processor — so if Sony Ericsson’s going for the whole one-with-keyboard-one-without twinsies idea here, we can probably expect something similar from this unnamed piece of kit.
Update: According to SEMC, the handset we’re looking at is called the Kanna and features a 3.2″ 360×640 display, Wi-Fi, 8.1 megapixel camera, and shoots video in full 720p. They say it ought to be announced on February 14th at Mobile World Congress.
