Apple's first foldable iPhone, potentially named iPhone Duo, is expected to start at approximately $2,000. The device is likely to feature a 5.5-inch outer screen and a 7.8-inch inner screen with a passport-like wide folding ratio.

The hardware specifications may include the A20 Pro chip and Apple's own C2 cellular modem. The camera system is rumored to consist of a wide-angle and ultra-wide-angle lens, though it lacks a long-range telephoto lens.

Apple is reportedly working on as durable hinge and software adjustments to automatically resize application interfaces for the two different screen sizes. While the company is aiming to minimize screen creases, they will not be completely eliminated.

Reuters reported that initial supply of the foldable iPhone will be extremely limited, which may lead toto increase in prices through third-party resellers.
