I ordered an iPhone 6 16Gb ATT with two year contract. In all the rush to checkout after the store was down for hours I guess either I misclicked or it didnt register my tap to change to 64Gb. I called my apple store and they said they should be able to accommodate me and exchange my iPhone given they have it in stock (lifesavers). I changed ups to hold for pickup and plan to be there at 9am (opening) to pickup my phone and go straight to the apple store, should get there at or before 10 depending on traffic. What are my chances they will have an iPhone 6 64Gb ATT Space Gray for an exchange? Maybe an exchange would be able to use their DOA stock? Wish I paid more attention during checkout and caught my mistake Any insight or advice would be greatly appreciated.
