Yo folks
Just a tip for people with a car-stereo that has a AUX input. Use the bottom-half of the headset cable that came together with the package when u bought the phone. There is a mic inside the bottom half of the cable.
Buy a cable at the local Electricity store with at both ends a 3,5 jacket. Plug it into the Car stereo, and voila, your MP3 phone became also a handsfree phone.
