No cell phone for me. The more I see people with them glued to their heads, the more I enjoy being unencumbered by one. Maybe that'll all go horribly wrong someday, but I, too, believe that if I need help, someone will help me. My husband knows my route and arrival estimate.

I do have address stickers on my bike that include our home phone and my husband's cell phone numbers, and want to do something a little more visible in that regard.
