Apple is expected to release a pair of iPhones, similar to what it did with the iPhone 5C and 5S. The phones will have faster processors, one with a 4.7-inch screen and the other with a 5.5-inch screen. This is a bit larger than the iPhone 5S, which has a 4-inch screen.
Apple hasn't released a lot of information about the new phones yet, but more details are expected to be revealed at the September 9th event. Its expected to talk about the new operating system, iOS 8, and a new smartwatch.
