Software built for folding
iPhone Duo runs iOS 27, which Apple says reacts as the phone folds, reorients when turned sideways and switches to the right display when flipped over. The large screen supports Split View multitasking, and StandBy works on either display, even when the phone isn't charging.
The phone also supports Siri AI, Apple's new version of Siri powered by Apple Intelligence. It is rolling out in beta in English with iOS 27, and Apple says it will not initially be available in the EU or in China.
Accessories and trade-ins
Apple is selling an iPhone Duo Folio with a built-in kickstand and a thin two-part iPhone Duo Case. Both work with MagSafe and Qi2 25W chargers. Apple Trade In offers a credit of $175 to $885 for an eligible iPhone 13 or newer, according to Apple.
