Here is an interesting story of some David Fitzherbert whose life was saved by the Blackberry smartphone he had in his pocket.

The phone lying in his breast pocket saved his life by stopping him from falling any further into a crack of ice.

He was skiing down a glacier in the Matterhorn and Monterosa peaks when he fell into the crevasse.

He said: “Fortunately, the extra inches of the Blackberry were enough to block the fall.”

The phone was rugged enough to work even after the ordeal. Fitzherbert said: “It was still working well enough for me to tell her (his wife) I was alive. I couldn’t believe it.”
