Higher-capacity versions could reach roughly $3,000, making it Apple’s most expensive smartphone to date. The iPhone Duo is expected to open like a book around a foldable inner display, support side-by-side apps and work with the Apple Pencil. It is also reportedly equipped with the A20 Pro chip, Apple’s C2 modem and two 48-megapixel rear cameras. Sales are expected to begin in October, with white and dark blue color options.
