Apple's upcoming 'iPhone 18 Fold' is rumored to be the company's most expensive smartphone yet, with prices starting at $2,100 and potentially reaching $2,300. Leaks suggest the foldable device will feature a 5.5-inch outer display and a 7.8-inch inner display, aiming to compete with rivals like Samsung and Google. The foldable is expected to launch next year, and Apple is reportedly developing a liquid metal hinge for enhanced durability. This move into the foldable market aims to revitalize sales amid declining trends in traditional smartphone sales.
