This makes me feel better. The lack of any movement or even a credit card charge has been driving me nuts. When I preordered my iPhone last year I’m pretty sure I had activity by Sunday night.Totally normal. I have done a lot of Apple preorders over the years. I have seen no movement on a launch day preorder until Tuesday evening or even Wednesday morning, then all of a sudden rapid progress from China to Alaska to Kentucky to your local hub.
Don't worry. You'll get it on the day they quoted. Don't expect it early though. Apple makes certain that never happens.
