Teens - Confessions

well, I have an iPod touch, and I depend on it for alot of things seriously, and that means I can't get rid of it. But , that is where I look at... Bad things. My school has an IP FILTER or some thing that blocks bad sites even on my ipod over safari. Is there any thing else that I can do,
2. Sometimes I you- know- what for no reason, why and how can I break the habit?
