The only major surprise with September 9's announcement of the iPhone Duo was its name. Up until the last minute, most rumors referred to it as the Ultra or Fold. It's otherwise exactly as predicted: a passport-shaped foldable that acts like a traditional iPhone when closed, but more like an iPad when it's open.

Apple has rolled out iOS 27, iPadOS 27, watchOS 27, tvOS and macOS Golden Gate, bringing new Siri AI features, Apple Intelligence updates and several system-wide improvements.

Apple has finally entered the foldable smartphone market with the launch of the iPhone Duo, marking a major change in the company’s iPhone lineup. The device was unveiled alongside the new iPhone 18 Pro and iPhone 18 Pro Max at Apple’s September 2026 event.
