There aren't too many rugged cell phones out there that are built to withstand harsher climates. For those who favor the great outdoors, the brand new Sanyo SCP-7050 from Sprint may be right for you. The rugged rubberized exterior of the phone is built according to military standards and is stated to withstand the effects of dust, shock, and vibration. And if you have a penchant for grand adventures, the SCP-7050 even comes with a built-in GPS that works very nicely with Telenav Navigator to give you turn-by-turn directions to your destination. Hand an extra unit to your buddy, and you can talk to each other via Sprint's Ready Link Push-to-Talk service as well. Sure, the phone is fairly basic without a lot of fancy multimedia features, but why bother with that when you're mingling with nature? You can go ahead and read the full review of the Sanyo SCP-7050 for all the details of this durable phone. It'll available for $149 after a two-year service agreement with Sprint.
