Changing your Apple iPhone settings to this date will kill it
Don't try this at home.
Changing the date on recent models of the iPhone to January 1 1970 will render it completely useless and unable to reboot.
Although the iPhone has only been around since Apple launched it in 2007, it has the option to change the date as far back as the start of the '70s.
When the phone is turned off and turned on again, it refuses to reboot, simply displaying the Apple home screen and going no further.
Attempting to reboot the phone by connecting it to iTunes does not work. Users have reported that the only way to have the phone fixed is to take it into an Apple Store.
The hack renders useless any iOS device with a 64 bit processor - the iPhone 5s, 6, 6 Plus, 6s and 6s Plus, the iPad Air 2, the iPad Mini 3 and 4, and the sixth-generation iPod Touch.
The bug was tested by several Reddit users, many of whom confirmed that when shut down, the device refused to reboot.
The glitch possibly depends on the time zone: users in America, with time zones behind GMT, were affected, but one user with the time zone set to Beijing did not. The iPhone stores the date in GMT, so in some time zones, changing to January 1 1970 will set its internal clock below zero, according to one Reddit user.
iPhones set the date automatically, but in its settings menu users can turn manually select the date, users can scroll back to January 1 1970. When the phone is rebooted, it is stuck at the white opening screen with the Apple logo.
YouTube user Zach Straley showed how the glitch affected his phone. Several other Reddit members shared similar videos.
