Malcolm Owen, AppleInsider:

According to the Apple website, orders in the United States for all combinations of color and capacity of the iPhone X are claimed to be “In Stock” for deliveries, with orders arriving with customers as soon as “Tomorrow.” This appears to apply to devices for all four major carriers, as well as the SIM-free variant.

Bottom line, supply has caught up with demand, and there’s still time to get an iPhone X in time for Festivus.
