**UPDATED**
I added a video tutorial for dyeing the back of the Sprint Touch Pro 2 battery cover, as well as pictures of the results. I also Dyed the Stylus.
*This video covers the dyeing of a case with the orange insert*.

Stock cover & stylus next to the dyed case (with orange insert dyed black) & stylus- Remember the cover needs to stay in the dye at least 10 minutes for it to dye the orange backing on the Sprint version. In addition, moving it around a bit while it's in the dye helps to get it in all the crevices. This insures no air bubbles are in the holes, preventing the dye from getting into the orange.

Here is a link to the Touch Pro "Official" thread on how to dye the battery cover on the original Touch Pro. (with over 1,000 posts)

The only thing I do differently is place it in a bowl of ice filled water & rub it with a soft cloth until all the additional dye comes off. I have found this also helps with the initial smell.
This is a great process that I used with exceptional results on multiple covers. I am hoping that some people here will take the plunge & post pictures of their newly colored phones in here so we can see all the possibilities!
Here is a writeup another user did on my video:

Here is a comparison shot of the Sprint TP 2 With & without the orange undercoating. I used my fingernail & a razor blade to remove the backing completely.
EDIT: After removing the undercoating & using the speakerphone I noticed a marked difference in the loudness & clarity. Keep in mind this will increase the sensitivity of the mute button. Should not really matter though since it is only used when you have the device face down in speakerphone mode.
If the mute button bothers you:
Here is a redneck fix for your issue. Take a 1" piece of black tape. Fold it over on itself. Remove the battery, insert one edge of the take into the top of the battery housing. Re-seat the battery. This will cause the battery to shift just enough to fix the mute button issue, and prevent the battery falling out so easily. It does not effect thy dynamics of the case.
Time to remove it on the other one!
ADDED: Video tutorial for removing the orange backing (Using a Hairdryer to heat the cover first helps)
