We can’t believe we even have to say this, but in case you were wondering: No, iOS 7 does not suddenly make your iPhone waterproof. If you heard that it does, whoever told you that is a big, fat liar.

The whole ‘iOS 7 makes your phone waterproof’ thing is a hoax apparently concocted by the merry pranksters of 4chan, who created an Apple-like ad (see below) that claims the company’s new mobile operating system, which launched last week, has the magic ability to keep moisture from frying users’ iPhones.

“Update to iOS 7 and become waterproof,” reads the ad, which goes on to claim that, “In an emergency, a smart-switch will shut off the phone’s power supply and corresponding components to prevent any damage to your iPhone’s delicate circuitry.”

This is, of course, a pile of nonsense – but we don’t have to explain that, right? You are all smart people who know that dunking your electronics buys you an instant ticket to Screwedville. Right? (Please, say yes!)
