[CES 2010] We thought that i-mate had called it quits where making rugged cellphones are concerned, but they are back with the 810-F which is a general bad-ass handset, capable of withstanding just about any abuse you throw at it. It complies with military specifications, which makes it shock, water, dust, cold and heat-proof (to a certain degree of course). Heck, we suppose driving your car over this wouldn’t hurt it one bit, and you can always continue chatting on the 810-F while you’re taking a shower. Pity about Windows Mobile 6.1 Professional as the operating system of choice though, it makes us think twice – no, three times before forking out $700 for this as it rolls out Stateside in a couple of weeks’ time. Check out its detailed specifications right after the jump.
