Apple claims hundreds of thousands of people have already upgraded to iOS 7, the divisive new operating system that makes your iPhone homescreen look like the colorful guts of a piñata. And while there are plenty of serviceable new features being discovered daily, one thing iOS 7 does not do is make your iPhone waterproof.

No, that's not a typo. As the Independent first reported that a fake ad is propagating the false claim that iOS 7 makes your phone's delicate electronics impervious to liquid. "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," says the advert.

This, of course, is 100 percent fiction. iOS 7 is software; your iPhone's electronics (the parts that actually fizzle out) are hardware.

Nevertheless, an extremely small sliver of gullible youngsters appear to be falling for it. (H/T: Business Insider for some of these)

A cursory search through Twitter, however, seems to indicate a different trend: People are more interested in perpetuating the prank than letting their phones go for a swim themselves.

The original advert appears to have been created by the denizens of 4chan, a forum where nice young men hang out on the internet. The lesson (clearly) is don't let your phone get wet. Bad things will happen.
