Docomo just released the new 906i and 706i series mobile phones. One of those phones is the F706i, built by Fujitsu. They are marketing this phone as “the thinnest waterproof phone in the world”. It has a 3.2Mp camera, I guess it would be useful and fun to use it to take some pictures while snorkeling, it can be submerged three meters. But what is more interesting is how these girls from the ItMedia 706i review are using it.
