The Japanese company Willcom, announced possibly the smallest mobile device in the world with its dimensions being 70x32x10,7mm and 32gram weight. The WX06A has a 1-inch OLED screen and despite its size it also offers e-mail services and features a camera.
As for the rest of its specs,due to its size, its battery could not be very powerful and offers only 2 hours talking time and 300 hours stand by time. It also features a microUSB slot.
Unfortunately the WX06A works only with PHS Japanese networks so we will not see it in Europe. Its price is still unknown.
