At the MWC Pepcom event earlier in the week we bumped into Sonim and its almost indestructible handset, the Sonim XP2 Spirit. The XP2 is a seriously tough set with the display covered in Gorilla Glass from Corning, a magnesium core, and a shell crafted with hardened rubber and fiberglass, all backed by a rather bold unconditional 3-year guarantee: you break it, they replace it. Sonim gave us an opportunity to try to destroy the thing, and… well, how could we turn down an offer to try and smash a phone? So with hammer and nail we give it an honest go — follow on to the video after the break to see who wins.
