Apple announced its first foldable iPhone, branded the iPhone Duo, on September 9, 2026, positioning it as a premium book-style device with a 7.6-inch inner display and 5.4-inch outer screen that supports advanced multitasking and Apple Pencil features. Priced from $1,999, the model uses an A20 Pro chip and enters production amid supply constraints similar to past limited launches, with pre-orders opening October 16 and availability set for October 23. This timeline reflects Apple's cautious approach to new form factors while responding to years of competition from Samsung Galaxy Z Fold and Google Pixel Fold models. Traders are closely watching any last-minute production or certification updates that could shift the exact availability window.
