Engadget is reporting that the iPhone X is available in many stores and online.

We can confirm many stores do indeed have it, while a few have limited inventory still. We got a 256GB in silver yesterday at a local AT&T store because they were still out of black and 64GB models, so we assume most of Engadget's story is most likely based from checking a handful of websites for availability.

Regardless, the X wasn't expected to be readily available until somewhere in 2018 begging the question whether demand has caught up with sales.
