A phony, but official looking ad, claims the new iOS7 update for the popular phones adds a “waterproofing” element.

The advertisement  -- which has popped up on Facebook and Twitter -- shows an iPad and an iPhone displayed next to a tagline saying, "A smart-switch will shut off the phone's power supply and corresponding components to prevent damage to your iPhone's delicate circuitry."

The advertisement also claims the waterproofing feature "is covered by Apple's warranty policy."

According to the International Business Times, “it appears that the sleek faux advertisement, which expertly mimicked an actual Apple ad, successfully fooled several iPhone users.”

Several people who admittedly tested out the feature took to Twitter, while others simply re-tweeted the information, adding to the confusion.

Others mocked those who doused their phones in water.

One Twitter user wrote: “If you've lost your iPhone from the iOS7 waterproof prank...you deserved it. Since when did a software update change the hardware.  #idiots”
