I have 100% confidence that, despite the lack of movement of my device, it will be here when Apple promised it. The same scenario plays out every year — some phones fly through the system with notifications and indications, while others seem to stagnate at various waypoints... but they all get where they are going and 99.999% of them arrive on time, as promised.
If you think about it, it's a pretty freaking amazing display of awesome logistics. Apple, UPS (and other carriers for other parts of the planet) tackle a Herculean task multiple times each year, and succeed in the extreme majority of cases.
