This is my transparent backplate on my 4S.. I don't really like the chrome, but it's whatever. Most of the time you can't even see the apple logo since there's such a glare on it lol
I also had trouble getting it on. Took a few tries, and one screw would go in on both sides, but the other would only go in on one side. It was strange..
And yes, this one has the newer metal screw posts. I know you said you wanted one without logos, but just in case, it's from CNN.cn
