I just take the "Oldschool" Idea...Never say anything that you don't want anyone else to here over ANY phone line!! weather its a land line,wireless or cellphone its still a network!! and as edvidenced by the FBI "wiretapping" scandal that just hit the news this week,and the fact that no network is "Totally" secure, I never discuss anything that may considerd "Illeagal" unless it is in person!
