A huge leak that appears to be from within Apple has revealed information about devices and features that the company plans to announce at a major event Tuesday, including details about a high-end version of the iPhone that will be called the “iPhone X.”

Over the weekend, two Apple-focused blogs, 9 to 5 Mac and MacRumors, published information pulled from what appears to be the final build of Apple's iOS 11 operating system. The software indicates that Apple will release three phones Tuesday: the iPhone 8, iPhone 8 Plus and iPhone X.
