“Update to iOS 7 and become waterproof” claims the ad (see above) explaining 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.”
Users who believed the advert reportedly upgraded their iPhones and dunked the devices to test the feature, only to find that they had broken the expensive gadgets. Some have taken to Twitter to vent their displeasure at being tricked. One user wrote “Ok whoever said IOS7 is waterproof GO F*** YOURSELF”.
