iPhone hardcore modding

Being in the possession of an iPhone 4S, like what it seems to be half a billion of other people, I'd like to have it stand out a bit. I've read about 2 possible hardware mods, one being the 'glowing Apple logo' one, that simply makes the Apple logo on the back of your phone light up when you use the phone, in the same way as the Macbook. The other one is giving your iPhone an other color, which I'm into a bit more, I seem to like the red colored ones. Have you had any experience with hardware modding/do you ever want to do it?
