Yep i do agree that this is a great fix, having done this myself.
Just make sure before doing anything to your DHD you set yourself up so you know which screws go where after you remove them. Also Lift the Sticker with the IMEI number on carefully if you rip it off forcefully you'll snap the volume ribbon.
It does work it also allows you to clean the speakers too and the camera len too.
