It doesn't sound as hardcore as its predecessor, the Boulder
-- but Verizon's just-introduced Rock is actually the company's most functional Casio G'zOne model to date. Though it looks quite similar to the outgoing model, the Rock's headlining addition is the so-called Triple Sensor -- something certain G-Shock owners might already be familiar with -- which allows the phone to offer an integrated thermometer, compass, and pedometer. It also features touch-sensitive music controls, a 2 megapixel cam, and -- you guessed it -- mil-spec 810F compliance for resistance to the everyday ails of the world like water, dust, and sun exposure. It'll be available online starting tomorrow for $199.99 on contract after rebate, while stores pick it up a few days later on the 30th.
