Apple’s first foldable, the iPhone Duo, has pre-orders starting Friday, October 16 at 5 a.m. PT, with units arriving October 23. Open, it is the thinnest iPhone yet with a 7.6-inch inner display that is 50 percent larger than the 18 Pro Max; closed, the 5.4-inch outer screen keeps it passport-sized. Built on A20 Pro with a titanium frame and precision hinge, it starts at $1,999 in Star White or Night Sky. This is the official launch window after the September 9 announcement—no more rumor status.
