Could this be the iPhone 7 release date?
Last month, we heard that the iPhone 7 and iPhone 7 Plus (or whatever they end up being called) could be released on September 16. Today, 9to5Mac revealed an AT&T retail schedule which suggests that the handsets may actually be launched later in September. The leaked schedule details AT&T's next two "merchandising reset hours", which should take place on September 9 and September 23. It's likely that AT&T is planning to start accepting pre-orders for the new iPhones on September 9, and release them on September 23 - two weeks later. If that happens, we assume that everyone else, including Apple itself, will launch the iPhone 7 and 7 Plus on September 23 as well.
We definitely must mention that, according to 9to5Mac, these AT&T merchandising reset hours may not be related to the new iPhones. While the website notes that a "major phone" is expected to be released by AT&T on September 23, this could be a different device (maybe the LG V20). Still, September 23 will be a Friday, and Apple has made it somewhat of a tradition to launch new iPhones on Fridays. Then again, September 16 is a Friday, too, so we'll just have to wait and see what happens.
