In New York, 11,447 cases of stolen iPhones and iPads were recorded in the first nine months of this year, a rise of 3,280 over the previous year. In those robberies, at least one person had been killed for their iPhone and others have been stabbed or violently attacked.
The picture is similar across the U.S. An IDG News Service investigation into cellphone thefts in San Francisco found one-quarter of the 579 robberies that took place between November and April this year involved a knife or a gun. Half of the robberies involved physical force.
