Apple's flagship foldable went on sale on Friday, and as is tradition, the Apple CEO was there to kick off the sales.

Crowds flocked around Apple Stores worldwide as the iPhone Duo went on sale. As is tradition, Apple's CEO opened the doors at one of the stores.

This time, though, it wasn't Tim Cook, nor was it in New York City. It was John Ternus, who took over as Apple CEO in September.

Ternus threw open the doors at 9:00 am local time at Apple Domain Northside, located in Austin, Texas. The store first opened in November 2017.

He was joined by Senior Vice President of Retail Deirdre O'Brien.

Generally, the CEO opens the Fifth Avenue location. Instead, that location was opened by Apple's senior vice president of Worldwide Marketing Greg Joswiak and Vice President of Stores and Retail Operations Vanessa Trigub.

Apple opened preorders for the iPhone Duo on October 16. On Friday, October 23, the iPhone Duo finally began making its way into customers' hands.
