Apple will be announcing the next-generation iPhone(s) on Tuesday, September 10, and their next-generation mobile operating system, iOS 7 won't be far behind. If the last two years are any indicator, iOS 7 could ship as soon as Wednesday, September 18. Code-named Innsbruck, iOS 7 was introduced by Apple during the WWDC 2013 keynote back on June 10. A radical visual departure from previous generations of iOS, it focuses on clarity by removing all but the most essential interface elements and shifting from buttons to tinted text, deference by getting out of the way of content and apps, and depth by building the entire experience around a physics and particle engine that moves, blurs, parallaxes, and layers in virtual 3D. It touches every app, every pixel, and likely very nearly every bit of the system. It ships this fall, and here's everything you need to know about it.
Note: This preview is based on information Apple has made publicly available, and our own analysis based on that information. In other words, no NDAs were broken during the course of this writing. It also means minor changes, cosmetic and functional, might have occurred in subsequent betas. We'll address those in a future update.
