I changed my shipping address after I entered the order. I really don't understand why they're placing that restriction on orders. Are people stealing credit cards to buy iPhones? Some other problem?
Anyway, I'll see if they generate an exception email or something. If it messes up the order, no big deal. I can live with my 3GS a couple of weeks longer. ; )
Btw, when you go to change the shipping address, they say:
"Also please note that a signature is required for delivery of your package(s), so we suggest you choose a shipping address, such as your workplace, where you know there will be someone to sign."
Gee, maybe there's a valid reason for having your order shipped somewhere other than your home. LOL
