Apple's new iPhone lineup includes the iPhone Duo, a foldable phone, and the iPhone 18 Pro and 18 Pro Max. According to spec sheets, the iPhone Duo and 18 Pro use Apple's C2 modem worldwide. The iPhone 18 Pro Max uses the C2 modem everywhere except in the US, where it likely uses a Qualcomm modem, as reported by MacRumors.

The iPhone Duo was unveiled at Apple's September event, with a starting price of $1,999 in the US market. It features an expanded display that can be used for work, content creation, and entertainment. Apple executives demonstrated the device running various apps, including Zoom, Slack, and Netflix. Analysts say the iPhone Duo's high price and Apple's lack of clear vision for its target buyer may confine it to a niche of wealthy early adopters.

The iPhone Duo's multitasking features have been praised, with some users wishing that Apple had implemented similar features on the iPad. The device allows for split-screen multitasking, including the ability to split-screen a video with an app. Apple's new CEO, John Ternus, has an engineering background and has been well-received in his first major press circuit.
