iPhone 8 and Apple Watch Series 3 are sold out in some places

Apple CEO Tim Cook cheers alongside Apple Store employees in Palo Alto, Calif. for the launch of the iPhone 8 on Sept. 22, 2017.

“Our users are really smart, so they can decide what they want, and we try to help guide them in our stores and I’m sure the carriers are doing the same thing. But we really like what we’re seeing,” Cook said.

Cook also said that a glitch in the new watch’s cellular connectivity, a bug that was picked up on by some reviewers, doesn’t appear to be stemming demand for the product.

“The issue is very minor, it will be fixed in a software update,” Cook told CNBC. “It has to do with the handoff between Wi-Fi and cellular, and we’ll fix that. It only happens in a rare number of cases. I’ve been using it for quite a while and it works great. So we’re very happy about it.”
