Over the weekend my wife purchased me a new iPhone 5s. While playing around with it, I've somehow managed to "hide" the Photos app. I've searched every screen and the folders I've created, but still can't find it. When I perform a search, it appears in the list. I can click on it and open it to see my photos, so I know the app is still installed. Any ideas where it might be hiding and how I can get it back to my home screen?
