Overview
- The iPhone Duo went on sale Friday and demand outpaced supply, with local quick‑commerce listings such as Blinkit in Delhi‑NCR selling out in five minutes and many online orders pushed into January 2027.
- Apple and suppliers warned of low final‑assembly yields for the foldable OLED panels and hinge, so Apple limited in‑store stock and advised staff to discourage walk‑in purchases to conserve inventory.
- The Duo ships with an exclusive iOS 27.1 build tailored to its foldable displays, and Apple has signaled a wider iOS 27.2 rollout next week that will extend new features to other iPhones.
- Apple updated its developer rules and the App Store to surface a new 'Made for iPhone Duo' label and requires apps to be built with the iOS 27.1 SDK or later to fully use the Duo’s inner display and vertical toolbars.
- Security researchers demonstrated a Duo jailbreak proof‑of‑concept on launch day while multiple users posted similar 'L‑shaped' inner‑screen cracks; Apple has been issuing replacements in some cases but constrained supply could complicate repairs.
