When you're completely waterproof, able to function in temperatures ranging from -4 to 140°F and withstand body slams from six feet above the concrete, you pretty much roll however you please. Thankfully, Sonim's bringing its latest ultra-rugged handset, the XP3, into the United States in March, meaning that you can finally abuse your handset without feeling all guilty afterwards. Specs wise, the US version of the GSM phone will pack quad-band EDGE support, GPS, Bluetooth, "flashlight mode," a glare-resistant 160 x 128-resolution display, an Opera Mini web browser, 3-megapixel camera and a 3-year no-questions-asked guarantee. Sadly, we've no price to share, but we don't suspect all that rigidity will come cheap.

Casio's G'zOne Boulder doesn't do much, but what it does do, it does anywhere, anytime and under (almost) any circumstances. After launching a few weeks back on Verizon, the ultra-rugged handset has been reviewed over at CNET, and needless to say, it managed to handle a few dips in the pool and a couple close encounters with a wall with nary an issue. Unfortunately, the phone faltered at handling its most important task: making calls. Call quality in San Francisco was said to be "hugely disappointing," with most calls sounding "crackly" with a dash of "static and echo" for good measure. The extra features (camera, multimedia player, V Cast, etc.) were all decent, but nothing truly stood out as phenomenal. Overall, the Boulder is probably only a safe bet if you're dead set on the design and toughness, but even still, we'd try out a few other hardcore handsets before settling on one with lackluster call quality.

It's been a tick since Motorola / Symbol's MC70 saw a notable refresh, but today Moto is announcing that the newest version of its rugged Enterprise Digital Assistant (EDA) will boast GPS capability. The firm claims that this addition will allow organizations with field-based employees to "track and manage dynamic, real-time tasking, as well as verify specific locations of activities and provide mobile workers with pinpoint navigation support to improve location-based productivity." Additionally, the device will still include barcode data and signature capture, WWAN, 802.11a/b/g and Bluetooth, and should be available for sale worldwide in Q1 of 2008.
