Alright.. is it the one within the red lines or the green lines you're talking about ? what's the real material made of on the real phone ?
I still think the Plastic shader can do this, as it looks like plastic/rubber to me. Check your shader settings and drop down the specular highlights to a minimum, below 5,5,5 so u won't get much specular reflections in the surface. I'm not sure but perhaps a bit of SSS on the rubber/plastic will make it look good too.
