You can install Lockinfo without Winterboard? I thought Lockinfo required Winterboard? Or do you only need winterboard if you want to modify the slider and stuff on the lockscreen?
Is there any way to get a different (slimmer) slider without Winterboard?
Winterboard has nothing to do with lockinfo. Downloading lockinfo doesn't require winterboard, and winterboard is not in the lockinfo filesystem.
Winterboard is for stupid nonsense like changing the swipe to unlock bar into a dildo, etc.
