Hi Aucky,
I´ve a Sony Ericsson Mobile Phone. Delivered with it was a headset with mircophone for hands free telephone use.
Something like this
I just put the microphone under the headset and use the recording fuction of the phone...
Works quite good - you just have to find a comfortable position for the mic.
Bye the way, if you also use the in ear piece, you can make phonecalls ;-)
