Several online sources have confirmed that Apple will hold an event on Wednesday, September 7, at which the iPhone 14 will be unveiled.
This is a departure from Apple’s typical Tuesday iPhone events. This is likely due to Labor Day falling on that Monday.
It is still unknown whether IOS 16 will be ready to release at the September event. This week, Apple released the 6th beta of IOS 16 which included mostly bug fixes and minor maintenance improvements.
