I'm in sort of a tough situation, as I'll be moving in the next few weeks, likely right around preorder time, but before the phones arrive. If I preorder online with my current address (paren'ts house) would I be able to call the next day and change my phone's shipping address to the new location, while also allowing another phone on our family's plan shipped to the old address? Essentially, I want two iphones shipped to differing addresses.
