iPhone 7 (or just the new 2016 iPhones) to be released in mid-September
According to Evan Blass (aka @evleaks), who is usually very reliable when it comes to these things, the next generation iPhones will be launched in the week starting September 12. Since Apple loves to start selling iPhones on Fridays, we might be looking at a September 16 release date. Obviously, at the moment, we can't really confirm anything.
As you'll notice, Evan Blass isn't using the iPhone 7 name when mentioning the upcoming iPhones. That's because Apple may not want to use the name for this year's iPhones, instead going with something like iPhone 6x (where x could mean almost anything). It's said that the 2016 iPhone models won't be significantly different from the iPhone 6s and 6s Plus, as major changes are seemingly saved for the 2017 iPhones, which should come with a completely overhauled design, and important new features.
