I am pretty sure, but not positive, that you have to ORDER it that way but there is a way of changing the shipping address afterwards. However, there are some stories on this forum of people doing that and their preorder getting completely messed up. I have had 1 or 2 iPhones delivered to my office on launch day in the past, but I dont think that is possible anymore.
After you get the tracking info, you could request UPS/FEDEX to hold at a store and pickup after work.
