After releasing a long line of rugged dumbphones, it looks like Casio has done the inevitable and given its durable G'zOne handsets the Android treatment. According to screen grabs sent in by two anonymous tipsters, the G'zOne Commando C771 combines a macho design with a 5 megapixel camera and unspecified version of the OS -- all while meeting military specifications for water, shock, and dust resistance, of course. No word on pricing, but both shots reveal it's slated to go on sale April 28th. For now, parse what you will from the product page, and find more photographic evidence after the break.
