iSkin's latest antibacterial case made for Apple's iPhone reminds us that a product's coolness is no defense against deadly bacteria. In fact, studies have shown that cell phones happen to be one of the filthiest objects imaginable--dirtier than a toilet seat, computer keyboard, or the bottom of a shoe. There's just something magical about the combination of spittle and your text-crazy hands that make mobile phones a germ's best friend. The antibacterial iSkin Revo case for the iPhone is due out this month with a price of $39. Until then, think twice before passing your iPhone around at a party.
