Here is something you don’t want to do with your iphone because it will have serious technological implications.
Turns out that if you’re really bored and decide to see what happens when you manually change your iPhone’s time settings to January 1, 1970, you can say goodbye to your phone. So what’s so damaging about that date? CNN Money offered a theory.
“January 1, 1970 is the earliest date you can set your iPhone to. If you turn your date and time settings to manual (please don’t do this), and scroll the calendar back as far as you can go (seriously, don’t do this), you can only go as far back as January 1, 1970,” CNN Money noted.
At midnight GMT on January 1, 1970, the world watched the dawn of Unix time, which became the basis for clocks and other devices including the iphone. And CNN Money theorized that if you’re not in the GMT time zone, scrolling back to January 1, 1970, might cause your iPhone to think you’re in a time before that date….
There’s a video of an iPhone user setting the device’s clock back to January 1, 1970. And then when the phone is powered off and back on again, it’s stuck forever on the greeting screen with no possible solution.
