I just open a sealed-in-box of iPhone 4S white version. However, the screen is so yellow tint that I don't want to look at it any more. Is it possible that I can still go to Apple Store and ask for a replacement and if possible, i can only get a refurbished one? But mine is just brand new. I heard that refurbished ones more or less have some issues and are used. What should I do? Thanks.
