Apple Executives Mark iPhone Duo Sales in New York and Austin

The highly anticipated iPhone Duo went on sale at Apple Store locations around the world today, Friday, October 23, drawing significant interest from customers. Apple released a statement this morning detailing the global launch activities, which included crowds gathering at its retail outlets and staff providing hands-on demonstrations of the device to attendees.

Apple's press materials state that stores were filled with customers as team members invited them to experience the new product. The company's senior vice president of worldwide marketing, Greg Joswiak, participated in the launch at Apple's flagship Fifth Avenue location in New York City, alongside Vanessa Trigub, an Apple retail executive.

In a separate event, Apple CEO John Ternus joined retail chief Deirdre O'Brien at the company's Domain NORTHSIDE location in Austin, Texas. This gathering in Austin coincided with other major events in the city this weekend. Apple is currently the exclusive streaming partner in the United States for Formula 1, and the United States Grand Prix is scheduled to take place in Austin.

Lines formed at Apple Stores worldwide overnight as customers sought to purchase the device through walk-in availability. Apple had previously cautioned that inventory for walk-in sales would be limited, a warning that appears to have materialized at retail locations. Staff members at Apple Stores have been advising shoppers who were unable to purchase a device to check the Apple Store app tomorrow at 10 a.m. ET for details on in-store inventory.

Apple has released photographs from its global launch events, and readers have also shared images from their local stores. The company has not provided any sales figures or comment on the level of demand for the iPhone Duo at this time.

The iPhone Duo is notable for being Apple's first foldable device. The launch is taking place across all of Apple's retail locations, with the company offering personalized shopping support to customers interested in the new model.

Looking ahead, customers who were unable to secure a device at a retail store today will have another opportunity tomorrow morning. The company's guidance directs interested parties to consult the Apple Store app for inventory updates, indicating that availability will be reviewed on a store-by-store basis. Apple has not commented on when it expects to have broader availability for the iPhone Duo, and no further information regarding future stock has been released.
