Much of the anticipation is swirling around whether Apple will show off a dramatically different type of iPhone with a sleeker and even bigger screen to celebrate the device’s 10th anniversary. Even if such a device is unveiled, Apple will also likely reveal upgrades to last year’s iPhone 7 and iPhone 7 Plus. (AP Photo/Alan Diaz)
