A tough, useful little flip has been announced on Verizon called the Casio G’zOne Rock. It had been previously spotted on a leaked roadmap, but few specifics were available.This phone looks like it would be a hikers dream, complete with compass, walking counter, thermometer, astro calendar, sunrise/sunset and tides apps to keep you oriented in the wild. It also features push-to-talk over EV-DO rev. A, a 2 megapixel camera, and meets MIL-STD-810F-grade ruggedization for impact, vibration, water, dust, extreme temperatures and just about anything else you could throw at it. The Rock joins the Boulder and Type-S in the G’zOne family of rugged handsets, but it’s tough to draw any real differentiation between them. The Casio Rock will run you $199.99 on contract after rebates starting tomorrow – just keep an eye out on the VZ store to pick it up.
