Apple has reportedly begun training AppleCare employees on iOS 7 related to support issues and it must be completed by the second week in September, according to 9to5Mac.

The question is why they have to train AppleCare employees on iOS 7? It is because of significant changes to the user interface in iOS 7 different than iOS 6 and they have to be ready to explain some customers who may be surprised and confused about how the new operating system works. During the launch of iOS 7, Apple will require its part-time support staff to work full-time for new iOS 7 launch. They also will be training to know about new iCloud Photo Sharing options, the revamped Camera app, the new features of the Safari browser, Control Center, AirDrop file-sharing, and the new iTunes Radio streaming music service.
