last month suddenly My original Nokia WH-205 headset stop working on my Nokia N900. I use this Headset on My laptop and other Nokia mobiles like 5800 it works fine. But it did not work on N900. So i search its solution on internet, I re-flash my N900 more then 10 times with different firmwares.

But at the last i decide to make a Experiment on this rubbish headset and i try to make it a normal headphone but just doing some work on its Jack.

A normal headphone have 2 cuts on its Jack and this headset have 3 cuts on its jack. Extra cut is definitely for microphone. So with this experiment i lost microphone connectivity with N900. But it was useless for me. So i use a soldering kit for all this and make my headset working
