A new iOS feature, called Activation Lock, disables the iPhone even if a thief has turned it off or erased the data on the phone. Some police officers have called for a feature like this — a “remote kill switch” that renders the stolen phone useless and difficult to sell in the black market. The phone can be reactivated only after the user logs into it with the right Apple ID and password.“We think this is going to be a great theft deterrent,” said Craig Federighi, Apple’s senior vice president for software engineering.Brian Chen – New York Times
