iPhone Remote / Mic Issues - Solved!

So I went through a set of the new iPhone 3GS headphones and purchased a replacement online. They worked for a bit and then people would complain that they could not hear me very well and the remote function (iPod start and stop) ceased to work. I noticed a pattern with regard to the call recipient's complaint about them not hearing me happening when I played with the headphone jack. I looked into the headphone jack hole a few times and didn't see anything. I figured it was time for a new set.

Fast forward a few weeks later. I got feed up with not being able to answer the phone, fast forward to new tracks, etc. with the remote mic and decided enough was enough. I turned the iPhone off and used a pin to dig to the bottom of the jack and pick out a few wads of pocket lint. Once cleaned, the remote mic worked perfectly.
