I got the beveled one from cnn.cn, a few thoughts:
Overall it looks nice and gives the phone a unique look; however, in my opinion it makes the phone feel cheaper than with the stock glass back. Not sure why, but the phone just feels better to me with the original back.
The screw holes are plastic compared to the metal ones ont he stock back, I was never really able to get them tight, which resulted in the screws falling out eventually. Now that I've lost them, the back slides off easy, which is annoying.
In most instance the camera doesn't appear to be effected; however, in some cases, because of the distance between the lens and the cover, you can notice dark circular corners on the edges.
As far as reception, its hard tell because reception is always pretty good in orlando, but it seems like there is a drop of at least a bar, sometimes two.
After using it on and off for about a week, I'm going back to stock, though I'll have to find some replacement screws :/
