iOS 7 may not be here yet, but developers have been hard at work creating jailbreak themes to simulate the look and feel of Apple's latest beta firmware. Of course, the key word is simulate, as many of the themes are simply new graphical elements and other skins that use Winterboard to camouflage icons.
For those who just can't wait until this fall to see what iOS 7 is all about, there are several free iOS 7 themes popping up in the Cydia jailbreak app store. Not only can the home screen be themed, but there are options for an iOS 7 style lock screen, status bar, control toggles, messages, and even the calculator. All of the themes require a jailbroken iPhone and Winterboard.
