Sony’s SO902iWP is an amphibious creature, featuring the ability to receive and make calls underwater. If that isn’t good enough then you like the ability to snap 1.3 megapixel photos in and out the deep blue. According to our friends over at Core77 this phone won’t make it beyond Japan’s shores, but if you do your digging you might find it emerging on a coast near you. What does it lack? Bluetooth of course; how fitting.
