Follow these easy rules and no one will hate you. It's as simple that.

Nobody Likes Your Ringtone - I'm pretty sure that 95% of ringtones out there are only cool to the people that purchase them. There's really no reason your phone should ever have to be off vibrate, since most phones can be felt buzzing even if you're a good ten feet away from them. Having your phone always on vibrate also helps you avoid being "that kid" in lecture who scrambles for twenty seconds as they try to keep their phone from blasting "This is Why I'm Hot" to the general amusement of the class.

You are Not Important Enough to Need a Bluetooth Earpiece - You're in college, you're not a stock broker, investment banker or Ari Gold. There is no reason you can't reach into your pocket, flip your phone open and raise it to your ear. Excuses that do not fly: "It helps keeps my safe when I'm driving." Do you really need two hands firmly on the wheel? Are you driving an offroad rally race? I drive with my thumb. And the distracting part of cell phone use is the talking, not the holding of the phone to your ear. Also there's the ever popular, "I'm saving myself from the harmful radiation." If it's true cell phones do cause cancer, we're going to be one dead country in about thirty years.

Cell Phone Accessories are Banned - Don't clip your phone to your belt. Why, why would you do that? It's just a shortcut to me saying, "Wow I don't ever want to be your friend." Your pocket is centimeters away, just go for it, stick it right down in there, it's OK. Also, why do people get phone covers? It's like when people get those protective bras for their cars. Yeah you're saving it from wear and tear, but now you've got this giant ugly thing covering it which makes it look far worse than it ever would through normal use. And it's not going to help when you drop it in your beer by accident anyways.

There you have it. These aren't hard rules and a little restraint goes a long way. Oh also, no bedazzling, under any circumstances.
