CWhisperer.
 

I have compiled CWhisperer for my n800 for fun. It seems to be working however I do not have a vulnerable cellphone headset to try it on.

PM for the zip. not sure if its correct for me to redistributing their software here.

Re: CWhisperer.
 

there's nothing against distributing files here.

but for the benefit of the community, you should upload it to garage.maemo.org
