My new Nokia 6230 came with a handsfree set with earbuds who were not as good as I had hoped, and I wanted to be able to use my own when listening to mp3 and radio. So I decided to do a little hack and install a standard 3.5mm headphone jack.

First I tried to do it on my own, but my skills with a soldering iron is not good at all, so I got a guy at a shop to do it cheap (100,- kr) for me. I think the result is great, and now I can use my nice Koss headphones with my mobile.
