maybe im wrong but didnt orders with different shipping addresses get cancelled in past launches? I wanted to do the same as I waited at my house for the iPhone 4s til 8pm at night as my ups guy comes by my house at the end of his route but comes by my work early in the morning at the beginning of his route. but I was afraid it would get cancelled so i left my home address but since I know him ill just tell him this week to bring it to my work first thing anyway hes done it for me before.
I hope they don't cancel my order, because my billing and shipping addresses are different. My shipping address is on file with my CC company as the primary shipping address though, so it should not be a problem.
fyi, just checked my CC and it has a pending payment on there from Apple, so looks good so far.
