Nothing in my tone of reply, you asked a question and I gave you an answer, you then asked your question again despite me giving you an answer. And it's you that wants an exchange, Apple have already got your money. I'd suggest you curb your attitude when you go into the storeErmmmm because they want my business perhaps?
Have you never returned something and exchanged for something cheaper and they refund the difference? You’d think I’m asking for it for free by the tone of your reply!
