Overview
- Apple introduced the iPhone Duo as its first foldable, a book‑style phone with a roughly 7.6‑inch inner display that can be used folded, half‑open or fully open.
- The Duo emphasizes engineered refinements: a custom variable‑torque hinge that holds open, a matte 'nano‑texture' inner screen meant to reduce the crease, and an under‑display selfie camera.
- Apple built a Duo‑specific version of iOS that adapts to the phone’s shape and supports split‑screen use and app pairing so apps can be linked and resumed across folds.
- The phone is pitched as an ultra‑premium ‘halo’ product with a starting price near £1,999 (about $2,000), and early coverage mixes strong design praise with doubts about its value for most users.
- Analysts and suppliers have warned of constrained early supply because of complex hinge production and tight advanced‑chip and memory allocations, and Apple plans preorders in October with shipments to follow later that month.
