Hello, I bought an Ipad 2 white 16g wi-fi on april 4th. Since it have been exchange one time for cosmetic problems (Bezel starting to separate from aluminium enclosure ). Yesterday, I decided to reserve a 16g in black. I no longer want the white Ipad because the cosmestic issues are more visible on white and turn me crazy. Thats my last day of return. My question is will they refund me so I can buy the black one ? The i pad they swap me got a different serial number that the one on my original box since they only swap the unit and not the box , will it cause any problem for the refund ?
