Apple released the iOS 7 update for iPhones last week, and pranksters (allegedly from 4chan) set to work creating a series of spoof ads claiming the update made iPhones waterproof.
Update to iOS 7 and become waterproof.
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.
Needless to say, the iOS 7 update does not make the iPhone waterproof.
It's not clear if anyone fell for the joke and tried dunking their iPhone in water. But a few people have been tweeting angry remarks about the hoax, such as, "Ok whoever said IOS7 is waterproof GO F*** YOURSELF". But it's hard to know if these tweeters are being serious, or just playing along with the joke. More info: independent.co.uk
