If you see this image (originally posted on the 4chan website), do NOT follow it’s advice, under any circumstances–it’s a trap!
Apparently there is a nasty bug on any 64-bit iOS device (such as an iPhone or iPad) that will cause the device not to no longer boot if the user sets the time and date to January 1, 1970. Even scarier, you cannot simply restore the iPhone at this point–you have to physically bring the bricked iPhone to your local Apple Store to have a hardware repair done on the device. This sinister date, 1/1/70, is basically an internal value of zero on a Unix operating system, which causes the software to crash, taking your iOS device along with it.
What should I do about this problem?
You would be wise to A.) not perform this trick yourself and B.) don’t allow anyone to perform this trick on your device unless you feel like traveling to the nearest Apple Store. This image circulating around the internet seen above is a terrible hoax and will brick your iOS device.
