The iPhone Duo arrives in stores tomorrow, and Apple has begun marking some early pre-orders with launch-day delivery as "shipped."
Users whose iPhone Duo delivery date is later than October 23 may be checking the Apple Store app regularly to see whether their delivery window has moved up. Customers who were quoted an October 23 estimate have another reason to check: their order status. Some users have begun reporting that Apple now says their iPhone Duo has officially shipped.
You can check your order status by opening the Apple Store app and going to the For You tab, where your iPhone Duo order and its latest status should appear at the top. Apple tracks orders through four stages: Processing, Preparing to Ship, Shipped, and Delivered.
If you were quoted an October 23 delivery but your order does not yet say shipped, there is no need to worry. iPhone pre-orders are always in transit before the app officially updates to reflect their shipping status.
