Will they leave the box at the door or does someone have to sign for it?
Did you order from Apple? If so log in to your account where it lists your shipment and tracking #. There you will see a link to "Pre Sign" for your shipment. Print it out and follow the instructions. I have used the form several times since I live in a good neighborhood and do not have to worry about packages being left at my house.
This option is not available with AT&T AFAIK.
