Installation and setup instructions of SwirlyScreen™
SwirlyScreen™ has no application icon of its own, so you cannot start it as an ordinary application. Instead, SwirlyScreen™ starts automatically as soon as you wake your iPhone up, i.e. when you press the Power button or press the Home Menu button.
After having installed SwirlyScreen™ from Cydia you must enable it! This is done in the iPhone's main Settings menu by navigating to: Settings->Cydget->Lock Cydgets. In this screen just make sure that SwirlyScreen is enabled by clicking it and place it on the top of all other cydgets. You may also disable the other cydgets if you so wish.
