ALBANY, N.Y. (AP) — New crime data show Apple’s addition of a “kill switch” to its iPhones last September has sharply reduced robberies and thefts, authorities said Thursday.

The report by state attorneys general, prosecutors, police and other officials from a year-old initiative called “Secure Our Smartphones” said 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.
