Hi, I have a smart cover coming up to a year old (PRODUCT RED one). However, it seems to be separating at the edges and is starting to look really tatty. These aren't cheap either, for the sake of £20 I'd buy a new one, but these cost £60. Are these covered by Apple Care, and if so, would they replace it? It doesn't frequently travel with me and I treat all my stuff well, except this case seems to hate me.
