Mentions iPhone Duo: “Ready for iPhone Duo: Fax fills the large inner display with Send and Receive side by side, and whatever you’re doing — editing a page, getting a number, reading a fax — carries on when you fold or unfold.”

Checked every few hours. Only builds made with the iOS 27.1 SDK, accepted since October 5, 2026, can use the whole inner display. Owner reports confirm whether an update did.
