What the fold changes
Closed, iPhone Duo is a pocket phone with a 5.4-inch outer screen. Open, the inner panel is Apple’s largest iPhone display, and iOS 27 moves the Dock and status items to the side so two Home Screen pages and Split View can sit next to each other. StandBy works on either display even when the phone is not charging.
The camera system is a Dual Fusion pair, not the iPhone 18 Pro’s variable-aperture main camera or 8x telephoto. The fold is what Apple is selling instead: rear-camera selfies with a live preview on the outer display, an under-display FaceTime camera for hands-free calls, and a hinge that holds the phone open flat.
Where to buy iPhone Duo
The Apple Store is the primary pre-order page, with Best Buy and U.S. carriers (AT&T, T-Mobile, and Verizon) expected to list the same storage tiers. Apple says iPhone Handoff, which keeps one phone number across two iPhones, launches with T-Mobile in the U.S. This tracker will be updated as color and storage SKUs show delivery dates.
