Let's be clear on this from the start - we wouldn't advise doing this.
One YouTuber is claiming that the latest iPhone is waterproof but we're very sceptical about it.
This sort of thing has been tried out before, only to turn out to be a trick. A few years back, a similar rumour led to people plonking their brand-spanking new iPhones in bowls of water. It was a hoax, and plenty completely ruined their new phones.
This video appears genuine but we're not convinced enough yet. If they are, it seems very strange that Apple forgot to mention the new feature when launching the new phone a few weeks ago.
