Sonim is back with another rugged handset at MWC this year with the XP3300 Force. The Force has one major feature going for it, the ability to offer the longest talk time of any cellphone in the world at 20 to 24 hours, or 20 to 24 hours of continuous GPS tracking, along with 800 hours of standby.

Sonim made this just as rugged as it’s other offerings, casting the Force in a fiberglass shell with 1.5 millimeters of Gorilla Glass over the display, all adding up to an IP-68-rated device that can survive a two-meter drop onto concrete, two meters of submersion in wastewater and temperatures ranging from 20 below zero to 55 degrees Celsius (-4 to 131 degrees Fahrenheit).

Some days I think working out in the open by myself would be welcome. Then I remember that there is no internet or AC out in the wild and come to my senses fast. Sonim has unveiled a new mobile phone for the folks who do work outdoors where things can get rough and the risk of bodily harm is high.

The handset is called the Sonim XP3 Sentinel and has an interesting help capability. The handset has a green button, amber button, and a red button. The red button immediately calls for help and sends GPS coordinates when pressed.

One of the most embarrassing things I have seen happen to a manufacturer at CES happened this year when Sonim challenged people to break its indestructible X3 handset. One guy from BBC succeeded, thwarting all claims of being indestructible. Sonim is showing off its new XP2 Spirit at MWC and letting people beat the thing up.

This time around, the handset is called “nearly unbreakable” and people are beating the device up pretty good with a tool belt featuring nails, wood, sand paper, and other torturous devices for which to work on the smartphone with. The handset is the firms first 3G offering.

Sonim Technologies knows how to make rugged handsets. The company has already released some pretty tough phones in the past, but now they have a few more models scheduled for a mid-2009 release. The newest additions are the Land Rover S1 and the Land Rover S2 G4. Both will come with a protective case made from XENOY, which is “a revolutionary post-consumer plastic derived mostly from used plastic bottles and film.”

The Land Rover range will of course feature water resistance and the ability to function in the hardest of environments, including 1.6 meter drops on something as unforgiving as concrete. No word on pricing, but you can expect to pay a premium when they’re available.
