Been using my iPhone 4 for about six days now with no rubber bumper, haven't had any problems. I played around with trying to diminish the signal but I've never naturally held my phone in a way that does. I work in a thick concrete building and it actually makes and receives calls in places that my 3GS couldn't, so as far as I'm concerned this thing about the antenna is way overblown.

Matt and Trey should make another episode where all the characters start using the name Muhammad as a generic nickname, like dude, and they all call each other Muhammad. Then they should introduce a bunch of random characters as the episode goes on, and one of them is inconspicuously the 'real' Muhammad, but they never say who it is. That should pretty much force Comedy Central to either censor the entire episode or admit what they did was stupid.
