In a few easy steps, I will go over the process of stopping those nasty bill collectors and/or anybody you just don't want to talk to anymore. (Only works on cell phones with memory chip slots or the ability to go on the Internet or text messaging abilities).
we will be stopping them, by assigning them names in your contact list and assigning those names a blank ringtone so that you will never hear them call you again.
Step 1: creating the silent sound file
step one involves your prep work...
unplug your microphone from your computer (if you have a mic)
open your sound recorder... usually "start- programs- accesories- entertainment- sound recorder.
hit "record" and then hit "stop" a second or two later.
go to file- save as-
name it "blank" or whatever you want and save it in a place you can remember, like the desktop.
