Fujitsu F-04B is a mobile phone that can be used separately between the touch screen (touch screen) with a QWERTY keyboard / keypad. Each unit (screen and keyboard) can be used on its own. We can use the screen without having to use a keyboard. The most fun when we use Fujitsu F-04B, when Fujitsu F-04B used for playing games, we can put the 3.4-inch screen on the table and we can hold the keyboard & use it as a joystick / game pad.
