Authorities say new crime data show Apple's addition of a "kill switch" to its iPhones last September has sharply reduced robberies and thefts.
New York Attorney General Eric Schneiderman says Thursday the data show crimes meanwhile surged against people carrying phones without switches intended to make them useless to thieves.
The report from a year-old initiative called "Secure Our Smartphones" says Google and Microsoft will incorporate a kill switch into the next version of their operating systems on smartphones.
The three systems - Android, iOS, and Windows Phone - are used in 97 percent of smartphones in the U.S.
In New York City, robberies of Apple products fell 19 percent in the first five months of 2014 compared with a year earlier. In San Francisco, iPhone robberies declined 38 percent.
