I've had my iPad 2 since they were released. It is one that has the light leek issue, which I read advice at the time ranging from it will go away to just live with it. I have AppleCare. Lately, the iPad is doing a couple of wonky things, displaying the icons on the screen in odd configurations to not responding to taps until several taps or only responding to holding down for the open dialogue box. I believe it's time to replace. is it possible to exchange at an Apple store or do I have to ship and wait? If, as I hope it can be exchanged, is my info transferable?
