It's that time of year again. Apple's next iPhone event will take place on September 9th at 10AM PT, live at the Bill Graham Civic Auditorium in San Francisco. This is expected to be the unveiling of the iPhone 6S and 6S Plus, which are reported to have animated wallpapers, 4K video capabilities, upgraded 12-megapixel cameras and front-facing flash, among other new features. We may even see something about force-touch iPhones. The event invite is light on details, as usual, but features the tease, "Hey Siri, give us a hint." So, of course, we asked Siri and have posted its responses below.
