For in-store pickups, there will be no movement until the day before where their back of house will start labeling devices for individual pickup. Operations at an Apple Store will be overnight as they get ready for an 8:00am open.
For those who pre-ordered and are having it shipped directly, Apple tends to not provide shipping information right away; thus why you might get a notification via UPS MyChoice before Apple.
You also have to remember, phones are heading to:
1. Apple stores.
2. Warehouses for each carrier.
3. Individuals.
Carriers will most likely be in possession of devices by Tuesday or Wednesday to get them into their customers’ hands (who ordered through them versus Apple) alongside their retail locations.
