I have the black Cinder and can tell you the hinge method will not work because the backing is bigger than the actual Cinder and it is solid black (in color and material) so no way to see the alignment with speaker and home button.
Also this back is in no way similar to the flimsy, easy to peel off we are used to. Its more of a hard protective support for the Cinder than a film.
I got the white one. What's your suggestion on peeling the back off without breaking the protector itself?
