UPDATE: What to Do If the January 1970 Hoax Broke Your iPhone
Apple has now created a support page for anyone who was duped by Internet trolls into resetting their iPhone's system date to January 1, 1970.
The hoax image, originally posted to 4chan, was falsely presented as a screenshot from the Apple website.
The pranksters claimed to be sharing the news of a retro mode on iPhones that could be enabled by setting the device’s date back 46 years.
Blast from the past
The original Macintosh introduced the world to computers, forever changing the way people experience technology, and allowing people to do things that were never possible before. With this easter egg, warp back in time with a class Macintosh theme to relive the magic on your iPhone. Change the date on your iPhone to January 1, 1970, press and hold the power button to reboot your device, and prepare for a wild ride!
Unfortunately anyone who does this will render their device unusable.
The bug affects iPhones, iPads and iPod Touches with 64-bit processors running iOS 8 or iOS 9, including the iPhone 5S or newer, the iPad Air, iPad mini 2 or the 2015 sixth generation iPod touch or newer.
Apple said it's working on an update that will fix the bug and if your device is inoperable because of this hoax, contact Apple Support.
Meantime, a YouTube video has been making the rounds, showing users how to fix the glitch themselves by opening up the phone.
However, experts caution that if you try this method and you damage the phone as a result, it will nullify your Apple warranty.
