Apple prepares iPhone Duo launch with limited stock and purchase caps

Apple's first foldable iPhone arrives with a premium price and an immediate supply squeeze. The iPhone Duo starts at $1,999, has a 7.58-inch inner display measured as a standard rectangle, and goes on sale on October 23, according to Make Tech Easier.

Preorders opened on October 16 and sold out almost immediately, Mashable reported. Delivery estimates soon stretched into 2027, making availability a central part of the launch before the phone had reached stores.

By October 19, Apple was limiting US customers to two iPhone Duos through its website and Apple Store app. MacRumors reported that attempts to order more triggered a notice explaining the cap.

On October 20, Applesfera reported that Apple's website and app were showing January 25 delivery for new reservations. But the queue was not moving uniformly: Mashable reported the same day that some buyers initially given 2027 estimates could receive their phones much sooner.

Apple also announced new and expanded American manufacturing partnerships on October 20, according to Apple Newsroom. The Next Web reported that Apple would buy up to $100 million of titanium from Pennsylvania producer Perryman over three years, for use in several products including the Duo's casing. That is a longer-term supply commitment, not a stated timetable for clearing the launch backlog.

The first reviews appeared on October 21. CNET praised the software integration and matte display while highlighting the $1,999 price. The Wall Street Journal Tech described an appealing folding phone with the trade-offs of a first generation product.

Also on October 21, Apple confirmed that stores would have limited quantities for launch day, The Verge reported. AppleInsider likewise reported that Apple Stores would have a small quantity available on October 23.

As of October 21, buyers have two uncertain routes: order online and face a potentially lengthy wait, or try for limited store stock on Friday. Improving estimates for some existing orders do not establish that the wider shortage has eased, based on the reports from Mashable and The Verge.

The early reviews also separate enthusiasm for the hardware from the question of whether to buy immediately. The Sydney Morning Herald praised the device but said many apps were not ready for its larger screen. CNET was more positive about the software experience, while still treating price as a major obstacle.

October 23 will provide the first test of how far Apple's limited walk-in stock stretches. The other immediate measure is whether improved delivery dates spread beyond the buyers described by Mashable, rather than leaving new orders waiting until January.

Software remains another unfinished part of the launch. Isena Code reported that Apple plans to add Reachability, its one-handed use feature, by the end of the year rather than having it ready when the Duo goes on sale.
