Problem with headsets pinouts for nokia n8

[fab]

Hello,
I've bought an headphone with microphone and remote control for the sound, certified for iphone.
At the beginning, i had no sound at all on my nokia n8 (headphones for the n8 had 3 pinouts, and this headphone have 4 pinouts, for compatibilty with iphones i guess). But i found these 2 interesting articles :

Then i bought an adaptater with 4 pinouts for the nokia n8. Since, i have sound, but the microphone and the remote control doesn't work.

Does anyone have an idea to solve that?

Thanks very much!
