For what it's worth, my response from T-Mobile on Twitter
Okay awesome! I appreciate you allowing me the time to look over the information on your order to make sure that everything is processing correctly. We want you to get your device in your hands ASAP! I checked into order # ********** and everything is processing successfully. If an order has successfully processed, the next step before getting it shipped out is that a shipping label has been created, which it has been with your tracking number *******************. This means that it can literally ship anytime so I would check this tracking number when you wake up and right before bed so you'll know exactly what's going on with this order.
