Part of NTT DoCoMo’s new line-up for March or April early next year, the Fujitsu F-04B is capable of splitting into two parts.

At first glance, the F-04B looks like a typical slider-type phone.  Upon closer examination however, you’ll note that the entire back half of the phone can be pulled off (after decoupling a catch), giving you an small phone with a 3.4 touchscreen display, radio module and antenna and a QWERTY keyboard with a slide-out numeric keypad.  The two halves remain connected via Bluetooth up to a distance of about 10 meters.

Aside from the tactile input, the lower half also has a speaker and mic so it can also be used to receive calls.  To alert you of incoming calls, the top of the phone has the ringer and vibrator while the bottom only carries a light.  As an interesting side note, you can also use the bottom half to make calls but you won’t be able to see the number you’re dialing when it’s detached from the top half.

The top half (where all the fun parts are)  has a screen resolution of 480 by 960 pixels, a Japanese and English interface, built-in Felica contactless smartcard, and a 12.2 megapixel camera.

Too bad it’s a Japan only phone :(.  If you want one, you’ll have to head on over to Japan.
