Your iPhone’s Lock screen and Notification Center are each home to a specialized interface for displaying the date and time along with a list of information notifications – this interface is known as the Dashboard.
That said, if you’re feeling a bit bored with the stock look and feel of the Dashboard, then perhaps you should try a new free jailbreak tweak called DashBored (pun intended) by iOS developer Smokin1337. As shown in the screenshot examples above, this tweak lets you customize the Dashboard’s colors, font, notifications, text, and much more.
