Hello. Purchased an ipad from an apple retail store, exchanged it later in the same store and my new unit has a terribly yellow display. I need to know quickly if I can return this ipad online for an exchange within the 14 days of receiving the brand new exchange, I also have AppleCare plus on this if that's noteworthy. Please I need an answer quickly. Can I return this online for a brand new exchange or am I going to need to drive hours to get to the store?
