Apple's rumored iPhone Fold will feature the "most significant overhaul" to the iPhone yet, according to Bloomberg reporter Mark Gurman. The foldable phone is expected to be a book-style foldable with a large inner screen for multitasking. The iOS 27 software update is set to allow the first Apple foldable to open apps side-by-side. Industry analyst Ming-Chi Kuo detailed specific design predictions for the device in 2025. The design could include a 5.5-inch outer screen that unfolds into a 7.8-inch internal screen, a hinge made from stainless steel and titanium alloy, battery cells, two rear cameras, a front-facing camera and a Touch ID side button. If the iPhone Fold materializes this year, expect it to cost around $2,000.
