I've had to restore twice because of Categories messing up. Can anyone tell me some ways that i can properly use Categories. I know that theres a message when you start the app warning you that using it could be dangerous but I didn't think I was using it improperly. Also since my iphone was restored this morning I don't have WinterBoard yet and my phone is running a lot faster. I want WinterBoard to set themes but I'd like to keep the phone from slowing down. What is it about WinterBoard that causes the phone to slow down?
