Here's yet another example of iOS 7's gesture-happy ways. In many of its built-in apps, you can flip back to the previous page by swiping left to right. Supporting apps include Safari (pictured), Notes, Messages, iTunes, Music and Mail. In Safari, you can swipe right to left to move forward in your browsing history, too. As it evolves, Swipe Back could very well become a preferred means of in-app navigation for many users.
