Apple has began accepting early orders for its iPhone X and shipping times quickly lengthened to as much as five weeks in the U.S., signaling supplies will likely remain tight as the new device goes on sale Nov. 3.

Apple stores in the US, UK, China, Japan and elsewhere show five to six weeks for delivery, while the Apple Store in Hong Kong says "no supply available." If you want it faster, the only other option is to join a line at an Apple retail store or buy off eBay for a markup. Otherwise, the only people getting an iPhone X on November 3rd were shopping online at 3AM in their underpants.

Those who ordered the phone in the first few minutes after the clock struck midnight in California will get their phones next Friday. And Apple also sets inventory aside for those buying at their physical stores. But its online stores from Europe to Asia showed waits of several weeks. In markets including Japan, Australia, and China, shipping times extended to as much as five or six weeks, while they reached three to four in Europe.

It's going to take some time to understand exactly why Apple's iPhone X is limited in stock, but reports have suggested the screen and Face ID components are to blame.

Shipping times of several weeks for major new Apple devices are common. Apple typically takes a few weeks or months to reach a balance of supply and demand for major new iPhone launches, and the 8's availability just weeks after its introduction may be a result of users waiting for the higher-end iPhone X.

Apple has said that iPhone X models will be available in its retail stores on Nov. 3 and encouraged customers to "arrive early".
