Not sure how big the market is for a waterproof phone, but here we have one. It’s the FOMA SO902iWP, and (for what it’s worth) can stay in water 1 meter deep for 30 minutes and still be usable.
That’s a very handy piece of functionality if you’re the kind of person who tends to operate your phone near water, or a good security feature for a huge clutz. Maybe you like to chat long hours in your hot bathtub, whatever it is, I’m sure someone will find a use for it. The phone also has a CMOS camera, no word on how well it performs under water.
