Mobile: A very robust handset for those working or playing sports outdoors from Sonim waterproof, dustproof, withstands falls, etc.

[PC Magazine] Great news for skiiers, blue-collar workers and anyone who tends to drop their phone in the sink: Sonim's XP3.20, the world's toughest phone, is arriving in the U.S. early this summer thanks to a group of rural mobile phone carriers. That means the phone is coming sooner than we heard in February.

The XP3.20 may also be available unlocked directly through some retailers for use on AT&T's and T-Mobile's networks, Sonim chief executive Bob Plaschke said Friday.

For instance, the XP3.20 has a rubber ridge around the screen and a few extra millimeters of space between the screen glass and the actual LCD display. That makes the display much harder to crack.

The XP3 can survive 100 9-foot drops to concrete (or more than 20 G-forces) and is certified to the IP67 standard, which is tougher than the usual IP57 standard you hear about. It's waterproof, dustproof, super-loud, and you can use it wearing gloves thanks to raised, ridged keys.
