It looks like typical Yanko-concept fare, but Elium Studio's Icon Phone is an actual working DECT/VoIP model. With a micro color screen, it's also a portable radio and alarm clock, but looks ever so sleek and minimal. [Elium via LikeCool]
I actually still have a home phone, and this is small with a radio/alarm clock. I am not sure how the "portable" part works, but, I like the small footprint and minimalist design. My only issue would be the use of it as an alarm clock; you cant really see the time on it, and I wake up a lot at night and look at the clock to see how long till I have to drag myself from bed.
