Apple announced its first foldable iPhone, the iPhone Duo, at the September 9, 2026 event under new CEO John Ternus, marking the largest design shift to the lineup since 2007. The book-style device features a 5.4-inch cover display and 7.6-inch inner screen, A20 Pro chip, in-house C2 modem, and starts at $1,999, with pre-orders opening October 16 and retail availability on October 23 alongside iPhone 18 Pro models. Supply-chain reports had confirmed component shipments and a fall 2026 timetable despite earlier production concerns, positioning the launch as a late but premium entry against Samsung and Huawei foldables. Traders monitoring resolution criteria should watch for any last-minute delays in shipping or certification, though current momentum points to on-schedule delivery.
