If you want at least a glimpse of the look and feel of the brand new iOS 7 which was released last week, you can help yourself with the wallpapers below. I took the originals (which you can find in this post) and cropped them a bit to be more suited for Windows or Android devices. The size is 1920×1440, so standrad ratio but it works well on widesreen devices also.
