iPhone Foldable Debut Sparks Global Rush as Stores Warn of Stock Shortfalls

Apple's first foldable smartphone, the iPhone Duo, went on sale at retail locations globally Friday, prompting lines to form overnight as customers attempted to secure a device without a pre-order.

The device's debut sparked gatherings at stores across the world, with the company releasing imagery from its international rollout. Customers filled retail spaces to participate in hands-on demonstrations and receive shopping support. However, walk-in availability was constrained by design. Apple previously noted that inventory for in-store purchases would be limited, a warning that materialized as queues formed and stock ran out.

Retail staff advised shoppers unable to purchase a unit on Friday to monitor the Apple Store app at 10 a.m. ET on Saturday for details regarding in-store inventory. The company is also fulfilling orders placed online for pickup at specific locations.

Executive leadership is marking the release at key locations. Greg Joswiak, Apple's senior vice president of worldwide marketing, is attending the launch at the company's flagship Fifth Avenue location in New York. He is joined there by Vanessa Trigub, an executive overseeing retail operations.

In Texas, Apple CEO John Ternus is present at the Domain NORTHSIDE store in Austin. He is accompanied by retail chief Deirdre O'Brien. Ternus had toured Apple's Austin offices earlier this week.

The launch in Austin coincides with the Formula 1 United States Grand Prix, which is taking place in the city this weekend. Apple is the exclusive Formula 1 streaming partner in the United States.

The crowds and inventory constraints reflect the high anticipation surrounding the device, which Apple is positioning as a significant new form factor for its mobile lineup. The company's retail network has served as the primary venue for consumers to engage with the foldable design.

Apple has not disclosed sales figures for the launch day. The company's press release focused on images from stores worldwide as customers lined up and staff provided demonstrations of the new device.

Shoppers who missed the initial wave of walk-in stock are being directed to the company's app for inventory updates on Saturday. The company continues to process orders for in-store pickup alongside its regular online delivery queue.
