I have a T-Mobile iPhone 5s 16gb Space Gray. It fell into a puddle and was standing upright in about two inches of water for no more than five seconds. I turned it off immediately, left it off for 48 hours in a bag of rice, still no luck. I can access the phone but the screen is completely squirrely, often typing and selecting things on its own and with "dead zones". A colleague told me that the Apple Store often replaces phones at no cost and I'm wondering if it's likely to happen for me?
