Apple’s first foldable, iPhone Duo, is no longer a rumor. Preorders are set for Friday, October 16, with stores and deliveries starting October 23, at $1,999 for 256GB in Star White or Night Sky. Official specs put a 5.4-inch outer display against a 7.6-inch inner panel, both sharing one aspect ratio, with A20 Pro, a C2 modem, and a dual-battery layout. The open question this week is not whether the hinge exists. It is whether a book-style iPhone at that price clears the first-week allocation Apple has been quietly building since the September 9 event.
