Hi Guys, The sleep button on my iphone 5 has started playing up. Maybe 1 in every 5 presses of it doesnt register. Its starting to get really annoying!! I havent dropped, or got it wet. Any ideas? Was thinking about booking in a "Repair or Service" at my closest apple store (30 miles away ). I have heard stories of people getting their phones replaced on the day at one of these appointments. Do they transfer everything over when they do this?
