I have callerID and don't answer unavailable calss most of the time. I got a number today on my ID but didn't say who the caller was. The area code was (435) which I found out was Cedar City Utah, does anyone by chance know of a bank located there??
online: www.411.com use the reverse lookup (you put in the phone number and it tells you who it is) Course, you could always call the number (NOT from your home, of course)
