Fujitsu has announced a new phone for the Japanese market, the F705i. The device's primary claim to fame is its waterproofing, which protects it from events such as rain or falling into a bathtub; it is safe at depths of up to 3.3 feet, where it can last as long as 30 minutes. The phone is also said to be the thinnest such phone in the world, measuring only half an inch thick when closed.

It does have other features however, such as a 2.7-inch QVGA LCD, a microSD slot, and a 1.3-megapixel camera. It runs on NTT DoCoMo's 3G FOMA network, and the back of the phone has a sub-surface LED display, able to display various words and characters. It should be carried by NTT starting today.
