Ever use your iDevice as an alarm clock? Ever have it mounted in your car and like to look at the time? Well now you can have your lockscreen be on until you hit the sleep button. Normally the lockscreen turns off or dims within a few seconds, but now you have the control. You can set the time you want it to dim, or not at all. Really useful if you have a dock or speaker dock for your device. Check out Lockscreen Dim Delay in Cydia for all devices.
