DockShift is a new iOS 7 jailbreak tweak that lets you change the look and feel of the iPhone dock by allowing you to change the background.

After installing the tweak, you can change the background of the iPhone dock from a number of backgrounds. You can also make the background of the dock transparent or more blurred by selecting the appropriate background via the Settings app (Settings > DockShift > Style).
