I don't leave my cell (a very nice HTC PDA with all kinds of stuff in it) in my pockets when I ride. One crash, or forgetting to empty my pockets before the spin cycle and it's gone. I put mine in my seat pack, in a plastic baggie in case I forget to remove it before washing my bike. When I crashed and totaled my frame a few months ago, the phone was fine, tucked away from the carnage against a soft spare tube.
