That is very useful... ...but about #2... ...Theres like 5 days till 2010... ...Most of the people I know DONT have land lines. To be honest, the majority of the time weve lived in our house (6 years) we didnt even have one. With the cell phones so popular, there really is very little reason to have a land line these days. Only times we had one it was because it was part of a tv/internet package. I never know the number, never gave it out. And the only calls we ever got were telemarketers, wrong numbers, or people trying to contact the previous number owners.
Another thing is, how do you know its a cell phone number? Unless they physically tell you its one, how?
