I thought this was very interesting not only for the concept in general of
using certain
frequencies to repel mosquitoes (although there are similar standalone
devices in the US
and elsewhere that purport to do the same) but more specifically by using
the mobile phone
itself as the device and platform to do this from.

Noise From Phone Can Chase Mosquitoes

SEOUL, South Korea - South Korea's largest mobile phone operator said
Thursday that it will offer cell phone users a new noise service that it
says will repel mosquitoes.
SK Telecom Co. said subscribers can pay 3,000 won (US$2.50) to download a
sound wave that is inaudible to human ears but annoys mosquitoes within a
range of three feet. Customers can then play the sound by hitting a few
buttons on their mobile phones.
The company claimed that the service worked during tests.
The service, which begins Monday, has one drawback: it consumes as much
battery power as normal cell phone rings.
SK Telecom has 17 million subscribers and controls a little over 50 percent
of the domestic market.
