Word! I just had to say it, nice.
Anyways, like others have mentioned the iKlear one works pretty well.
On a side note, I have 2 of the iPhone clothes ;p I had to return my first iPhone because of a dead pixel and when I asked if I could keep my old clothe too he said, "Sure, no problem."
thanks i think i'm gonna stop at apple on the way home to get me some of the iKlear stuff and i figure that if i ask very nicely at the genius bar they "might be able to give me a cleaning cloth from the back"... never hurts to ask!
