For those of you who pocket the cell phones, do you also ziploc it? Mine gets so sweaty in my jersey pocket that I'm afraid I'm going to ruin it. So I've kind of stopped carrying it unless I'm realllly going out in the middle of nowhere (where it probably wouldn't work anyway).

The map function is helpful, but I have no one here I could call if I needed a ride, etc. and pretty much stay in populated areas where anyone could call 911. I guess I just don't see it as necessary for a ride, but my family would prefer I carry it.
