KDDI's au network in Japan has revealed that it'll be stocking the slender Fujitsu Arrows ES IS12F starting January 2012. Fujitsu fans may recall seeing a very similar handset with the same (mostly) 6.7mm profile when NTT DoCoMo's version sashayed into those stuffy FCC offices. The phone runs on a single core processor, which is responsible for powering the image-stabilizing five megapixel camera and Gingerbread OS. The 4-inch, 480 x 800 AMOLED screen is cocooned in the same water resistant armor found on other Arrows devices, helping to protect those essential keitai functions like the One-Seg digital TV tuner and IR receiver. The skinny smartphone will go on sale in both black and red options for KIDDI, while NTT DoCoMo customers will have to settle for black.
