It will not change until they actually pack the phone. The way best buy does it or at least did it when i worked there...is the closest store that had the phone, would receive an alert for an order to be picked and packed. If you ever go into a bestbuy and a worker walking with a scanner tool and putting items in a cart or holding items, that's most likely what he's doing.
Anyways, In our case the phone. Once the worker actually scans the device'upc and imei barcode thats on the box, the system then generates a shipping label. The phone then sits for about 5-10 minutes while the carrier activates the phone on their end.
If the phone is "unlocked" then the phone is just packaged up. While the phone sits awaiting activation, the customer receives info that the package has shipped or in some cases, your order is ready for pickup.
The issue with this when i worked there is that for one, best buy NEVER knows what their preorder inventory will be. Not only that but best buy used to and I'm sure still does, ship orders from the closest store to customer. They would ship from minnesota or other warehouses when stores dont have the item in stock.
With that said, "Best Buy stores" are not only getting preorders for in-store preorders pickups but online preorders that has to be shipped. Also there is a queue as well when orders/preorders are placed online. However the queue can only be seen in the system at the store or location that the phone is actually shipping from. So if your order is shipping out of a New York store and you call customer services to ask about the que, they wont be able to tell you how many orders is ahead of you etc.
Same with in-store preorders. In most cases, it was just a sign up sheet. They would skip over people all the time with that one.
