Theyre certainly capable of 20hz and 12.3khz, which is mosquito-repellant. As for 50-90khz, i doubt it. Normally a special ultrasonic transducer is required for that.

@meths don't use the word crappy in the same sentence as mobile phone! You'll only get @a_p_a_n_k_y on his high horse
It's a phone not a getto blaster!
(thought I'd save @a_p_a_n_k_y the post)

I tried something simular on a 6600 and there was no actual sound coming from the speaker.... But the vibration motor was goin crazy... Could this be where the high pitch frequencies are comin from?

The mozzy things you can get off of QVC plug into a wall socket, emit no noise we can hear, and have a massively high pitch. You need specially designed equipment to produce the noise, and mobiles ain't it!

@energetic: Quite clearly the crappy speakers in mobile phones do not have the range of pitch to kill a mozzy so why bother?
High frequency sounds wont kill a mosquito but will keep it away from the source.
However as far as I know, high frequency sounds can be heard by animals and yesterday when I was trying the software, the sounds didnt seem to bother my dog. Perhaps on a different frequency this may happen. I read somewhere on an article that ultrasonic sounds can repel mosquitos, bats, rats etc which frequency is way to high than the P900 can produce. The ultrasonic sounds can be produced by a special appliance that is plugged into the electrical socket similar to the one that is mentioned before and that why it cannot be heard by humans.
I have my doubts that this software doesnt do what is supposed to do and maybe it will be a waste of money for someone to purchase it.
