It's a fact of digital life: You have to keep all of your devices updated in order to keep them safe from hackers, scammers, viruses and system failures.
With that being said, remember when we told you NOT to set your phone's date to January 1, 1970? Doing so causes the gadget to "brick" or lock up on the next reboot. In fact, the device locks up so completely, even an iTunes restore won't get it working again. You'll need to get a replacement gadget from Apple.
While it might seem like common sense not to set your phone's date back to the 70s, two security researchers have discovered a way to exploit and automate the problem with about $120 in equipment and a basic understanding of networking.
It sounds scary, but all you have to do to stay protected is get the latest update from Apple. On your iPhone or iPad, all you need to do is go to Settings>>General>>Software Update.
