jumped its own gun by a week, launching the rugged Adventure V750 today for a penny under $100 on contract after rebates. The phone becomes the very first on Verizon's network to support Rev. A-based push-to-talk, a quantum leap in robustness and functionality over the older 1xRTT fare; the G'zOne Boulder is expected in the next few weeks, bringing Big Red a pair of durable units that should appeal to the typical PTT crowd. Buyers of the V750 can expect a 2 megapixel camera, external music controls, microSD expansion, GPS, and of course EV-DO Rev. A data, so it's a pretty well-spec'd setup considering its lot in life.
