Just got off a chat with sprint...
I've been told that "Once inventory is received, your item will be shipped to the address you provided. An email containing the tracking number for your order will be sent to the email address we have on file. It is very possible that we have already received the inventory at our warehouse however the information is not updated yet. I would recommend checking back tomorrow during a business day as that is when the warehouse would update this information."
All the iPhone cargo jets have safely arrived in Louisville this morning. They're probably getting molested by customs agent right now and then a short road trip to the Sprint warehouse.
