For those that want to exchange model/memory size/color I purchased initial phone on apple store pre order for in store pickup so i count as a in store purchase. Not sure of that matters What is the best way to do so? I am on a subsidized phone so i cant buy online on apple store app do i need to just go to store and ask them to exchange from a certain stock? Is it easier or possible to have apple send you the phone you want and then return mine? Does the 14 day period just count from the moment you told them you wanted to exchange?
