A ringtone that doesn't bite...

Teens in Britain are downloading a ringtone that is in a high-range frequency which many adults can't hear, but most teens can.

"Downloading the sound, or another ring tone in that same high-frequency range, allows them to hear their cellphones ring when their parents and teachers (mostly) cannot."

Originally designed as a "no loitering"/teen repellant sound for retail stores and such, British teens are turning the tables. Via CoolBusinessIdeas via The Washington Post.
