Was talking with my 14yr old and she was showing me that high pitched tone ‘thing’ on her itouch. She was experimenting and showing me how she could hear it when I couldn’t. She said its like those deterents they were talking about using outside places they didn’t want ‘teenagers’ gathering. Interesting bit, she said a lotof young people using this as a text alert or incoming call alert so that they know they have a text or call, yet their parents can’t hear it, (or teachers in school). Its scary what they do with technology.
