Apple and its carrier partners have begun shipping iPhone 6s and iPhone 6s Plus pre-orders ahead of their launch on Friday, September 25. But don’t get too excited just yet, because this doesn’t mean you’ll get your shiny new iPhone early.

Customers in a number of iPhone 6s launch markets saw their orders change from “Processing Items” to “Preparing for Shipment” last Wednesday, and Apple began charging credit and debit cards. Now many orders are changing to “Shipped.”

MacRumors reports that orders placed with Apple and carrier partners such as T-Mobile and Verizon are now being shipped directly from China. This does not mean, however, that handsets will be received before the September 25 launch day.

Not only do these devices have a long way to travel, but Apple also works closely with carriers, retailers, and even distributors to ensure that its new devices aren’t delivered early. A small few do slip through the net every year, but the vast majority are held until launch day.

If you’ve already received a shipping notification, then, check it carefully and you should find that your device won’t actually be dispatched until Thursday, September 24, when it will be sent with overnight shipping for Friday delivery.

And if you haven’t received a shipping notification yet, don’t panic. Apple has million of orders to get through, and while that will take time, you should still see your device on launch day if the model you selected was still available for September 25 delivery when you ordered.
