Mosquito repelling ringtones

Someone says marketers are lacking creativity. Well, after reading today’s news on CNETAsia I have to dissent.
A brilliant (?!) marketer at SK Telecom, a Korean cell phone service provider, has invented a mosquito repelling tone. For 3,000 won (US$2.50), users can download a sound file which is inaudible to the human ear but helps ward off mosquitoes within a one-meter radius, the firm said.
Well, I don’t know if it works for mosquitos, but I’m sure this announcement creates a “buzz”
