Apple is likely to release the iPhone 7 on September 23 following a preorder period that’ll begin on September 9. This release timeline fits with that of previous iPhones and the exact date comes from 9to5Mac, which learned about the September 23 release from internal AT&T information.
The phone is expected to launch on September 7. Apple’s timeline for the iPhone 7 has repeatedly been confirmed through leaks, such as those shared by Evan Blass, who says the phone will go up for preorder on September 9.
Given how close we are to the unveiling, Apple will probably send out invitations next week.
