"Thefts of iPhones in London fell by 24% in the first five months of 2014 compared to 2013, while in San Francisco they fell by 38%, and in New York by 19%, according to data from the New York attorney general's 'Secure Our Smartphones' initiative, following the introduction of the kill switch – officially called "activation lock" – feature in the iOS 7 mobile software which lets owners remotely wipe and lock their phones if they are stolen."
