This phone, with a clever title of CUin5 concept phone, has no screen.  Gasp!  It does have six speakers and six microphones, though!

Whichever side you touch lights up, and all of the other ones shut up tight so you can’t click those buttons.  You can only call people, which is definitely a fatal downside to this phone.  I think that this is a cool concept phone that will never be much more than a concept.
