The original dock connector was getting less and less useful. I thing excessive use of my iPhone has caused this.
I followed the guide but skipped a few steps. It is not really necessary to remove the logic board completely to remove the speaker enclosure. You have to be very carefully thought, because you have to get the enclosure from underneath the logic board...
Be very careful! I missed the electronic components on the downside of the home-button-cable. I handled it to rough... I think I broke it. So, I had to replace this cable too.
Be sure not to loose any of the screws and keep them together per instruction of the guide.
