I recently returned my Black iPhone 5 and hope to get a White iPhone 5. So instead of refunding my CC, I just had them issue me a gift card since I was going to be purchasing an iPhone anyway. I am trying to prep my account so I can make the 10:00 preorder as quick as possible by adding the Gift card. However I cannot seem to locate the area to insert the Gift Card numbers. I thought it would be under billing but that is only showing an option for CC only. Where do I insert the numbers on the Apple Online Store?
Any help would be greatly appreciative
