Anti-mosquitoes service from South Korea Mobiles

Anti-mosquitoes service from South Korea Mobiles. A mobile phone operator in South Korea is offering users a new service that claims to repel mosquitoes during Korea’s hot summer.

Koreans will be able to download a sound wave that humans cannot hear, but that annoys mosquitoes within a range of one metre. We aren't sure whether its an application or just a sound. It costs $2.5.
