The best way to describe iOS 7's new redesigned interface is that it looks like a crystal-clear pane of layered glass with elegant "flat" icons and features. Simple and clean, Cook said, it is the "most significant
iOS update since the original iPhone [debuted]." iOS 7 will be available on the iPhone 4 and newer, iPad
2 and newer, iPad Mini and the fifth-generation of iPod
Touch, starting in the fall. Developers can start playing
with a beta version of the new operating system
today.
