Fujitsu and Sony both showcased new devices at the World Mobile Congress that are waterproof. The Sony Xperia Z and the Fujitsu Stylistic S01 brag that they can be held under fresh water for up to 30 minutes. While it might not be best to push your luck by using it in the bathroom it may offer peace of mind for some consumers. the Stylistic S01, running Google's Android software, will be available through Orange in France in June 2013 with a U.K. launch expected soon afterwards. Sony's Xperia, another Android device, is launching globally in the first-quarter of 2013 and retails at around $800.
