The good news is that the phone still can make calls and still receives them, too. That's how the phone was found, by hearing it ringing though it was buried deep in the dirt. The owner of the phone, Ossi Pyykkönen, was so impressed by the ruggedness of the phone that he plans on buying a new one to replace the smashed model.
Actually, the Nokia Lumia 920's toughness should be no surprise to our loyal readers who have seen the device get tortured before and work as though nothing had happened.
