Ok, so I have reviewed a lot of threads about the shipping/billing address confusion but most have been pre-orders through Apple. When I pre-ordered through ATT it gave me the option to complete an address for billing and one for shipping. Id like it shipped to my job since I know someone will be there to sign for it so I changed my shipping address to my work and kept my billing address as home. So since I ordered through ATT, this should be fine correct? Or do I have to go into Apple's site and change something there?? Just want to cover all my bases and make sure my order isnt cancelled because of a different shipping/billing address. Thanks for any info in advance.
