We dropped it, we dragged it behind a car, we even hammered nails with it. The Sonim XP3.20 Quest is the world's toughest phone. I'm very happy it say it's finally going on sale in the US today, at bestbuy.com and at some Best Buy Mobile stores in the US.

To find out more about the Quest, read our review and check out my torture test video, where I do things like chip it out of a block of ice with a chisel. The unlocked GSM Quest works with existing AT&T and T-Mobile subscriptions, and it has a pretty decent feature set along with its ruggedness: there's a 2-megapixel camera, an FM radio and an MP3 player. The phone also has the best warranty in the business. If you break it within three years, Sonim will replace it, no questions asked.
