Apple released iOS 7 on Wednesday of last week, and now more than 200 million devices are already running the new version of the operating system. The news came as part of a press release announcing the sale of 9 million new iPhone 5s and 5c models. That's quite an uptick from last year, when Apple announced - along with sales of 5 million iPhone 5 phones - that 100 million devices had been upgraded to iOS 6.
iOS 7 is the most ambitious update to iOS since its first release. In addition to a singificant overhaul to the user interface, getting rid of most of the skeuomorphic elements that were the hallmark of ousted Apple VP Scott Forstall, iOS 7 also makes many under-the-hood changes like improved multitasking, incorporating new features like AirDrop, Control Center, and more.
