The iPhone 7 is, in Apple’s own words, “the best, most advanced iPhone ever.” It is not, however, impossible to hack. A teenage hacker has found a way to circumvent the phone’s security and restrictions, jailbreaking a brand new iPhone 7 running iOS 10, effectively taking full control of it and allowing him to install apps not approved by Apple. The 19-year-old hacker, who’s known online as qwertyoruiop but whose real name is Luca Todesco, took advantage of a series of bugs he found and exploited—and all it took him, he said, was just 24 hours.
