I plan on preordering the AT&T iPhone 7 at 3:01AM EST sharp tomorrow. Can I change the shipping address to my work address with no issues? I can change it right now on the Apple Store app, Account, Primary shipping. Or if I recall from past preorders, the shipping address can be changed during the checkout process or it can be edited after the order has been placed as long as the order status is Order confirmation. I just want to make sure that my order does not get loused up by changing the shipping address. Also, if we get in early enough, will the delivery date be Friday 9/16? TIA!
