Kyocera DuraPlus (Sprint)

At 5.3 by 2.2 by .9 inches (HWD) and a whopping 6.7 ounces, the Kyocera DuraPlus is one of the biggest cell phones we've seen.

The DuraPlus is made mostly of grippy, scratch-resistant, rubberized black casing, with some metallic accents on the front.

The DuraPlus is a rugged phone that meets military specification 810G, which makes it resistant to dust, extreme temperatures, low pressure, rain, salt fog, shock, and vibration, among other rough conditions. It can also be submerged in up to 3 feet of water for 30 minutes.

There's a surprisingly powerful LED flashlight on top of the DuraPlus, which may come in handy depending on your work environment.

You need to be in a Sprint coverage area in order to use the DuraPlus, but you can still make push-to-talk calls to Nextel iDEN subscribers.
