Shipping estimates for the iPhone X have improved to 1 to 2 weeks in the United States, Canada, and Puerto Rico, suggesting Apple's efforts to ramp up production have successfully resulted in greater supply.

The 1 to 2 week shipping estimates are an improvement over the previous 2 to 3 week shipping estimates that have been available since November 15. iPhone X models ordered today in the United States and Canada will now arrive by early December, well ahead of the holidays.

For Europe, Asia Pacific, and the Middle East, iPhone X shipping estimates are still at 2 to 3 weeks, but those estimates should also improve over the course of the next few days.

In addition to improving shipping estimates for devices purchased now from the online Apple Store, Apple has also been sending out iPhone X pre-orders more quickly than expected. Many MacRumors readers who had late November and December shipping estimates after ordering have already received their devices or are expecting them soon.

Apple retail stores are also receiving regular shipments and customers who check stock on Apple.com early in the morning and use stock-tracking tools like iStockNow have been able to make purchases with no wait time.

Back in early November, Apple CEO Tim Cook said Apple was working to ramp up iPhone X production week by week, with the aim of getting the new smartphone out to customers "as soon as possible."

Ahead of the iPhone X launch, rumors suggested the device would be heavily constrained and in short supply until well into 2018, but given the improvements we're already seeing, supply/demand balance will likely be reached earlier than originally expected.
