Japan's KDDI just announced an incredibly slim and waterproof handset that goes by the name Arrows ES IS12F. Measuring just 6.7mm thick at its thinnest point (and 8.5mm at its thickest), this 105gram Fujitsu-manufactured Android 2.3 device is actually 0.4mm thinner than the Motorola Droid RAZR, while still boasting a 4-inch AMOLED display with 480 x 800 pixel resolution and image stabilized 5 megapixel camera. Inside you'll find a 1.4GHz Snapdragon MSM8655, 802.11n Wi-Fi, Bluetooth 2.1 + EDR, both CDMA and GSM radios for global roaming, and a 1,400mAh battery rated for 400 minutes of talk time. You'll also find local Japanese customizations like 1-Seg digital video, Infrared, and Mobile Wallet touch and pay support when it launches in January of next year.
This recommencement of the battle for the world's thinnest handset takes us back to 2006 when companies like Samsung and Motorola were slugging it out, millimeter by millimeter. Things got so nasty that a video (embedded below) said to have been produced by Motorola was leaked showing just how easy it was to snap Samsung's 6.9mm SGH-X820 handset in two — the "world's thinnest" cellphone at the time. Let's hope the Gorilla Glass used on the Arrows ES' 4-inch display provides just a tad more rigidity.
