iOS 7 allows you to set dynamic and panoramic wallpapers. However, it also comes with couple of new static wallpapers.
You can download them to get a feel of iOS 7 on your iPhone 5 running iOS 6.x.
Visit this page on your iPhone 5, tap on hold on the images below or tap on the download link to save the image, launch the Settings app and navigate to Brightness and Wallpaper to set it as the wallpaper on the home screen or lock screen or both.
We’ll update the post with the iOS 7 wallpapers for other iOS devices as soon as possible.
