Mosquito Repellent Mobile Phone
SK Telecom has come up with a downloadable application for their mobile phones that may find a loyal audience. They claim they’ve created a mobile phone-based mosquito repellent. Basically, it sounds like a ringtone that produces a sound undetectable to human ears, but which annoys mosquitoes. Of course, they want you to pay every time you use it. Still, it is a creative mobile phone app, whether or not it actually works.
