That is VERY true - it works on cell phones as well including TEXTS - they can spoof the sender - a friend was involved with a guy and another girl wanted her out of the picture so the other girl sent HERSELF nasty ignorant texts using my friends number - and of course, since it had my friends number on it - the guy believed the other girl..
I believe those services should be illegal or it should be a crime to falsely identify yourself especially when we pay for the phone service and services they are using - meaning calling our phones.
