Has anyone ever done a color swap at the Apple Store? My Black iPad Mini is preparing for shipment so it will arrive 11/2 but now I want White. If I go to the Apple Store then do I have to wait in line for a color swap? If this is how it works then its a good way to bypass the two week delivery delay since local stores tend to have better inventory than online. Also, I purchased with my Discover card for 5% Cash Back on online purchases so Im curious if they do a return/rebuy (which makes me ineligible since its no longer a Discover online purchase) or if they just do an exchange (which doesnt indicate to Discover that anything happened). Thanks.
