Your iPhone may be a powerful device but it is not designed to handle water accidents. You could always pick up a waterproof case for it. Getting your phone treated with Liquipel 2.0 is a much better idea though. Liquipel makes your phone watersafe. The second version is 100 times more effective than its predecessor. A device thoroughly treated with Liquipel 2.0 can actually achieve a liquid protection rating of at least IPX7. You can get your phone treated with this in the U.S and through Liquipel partners.
