I just got my black Pexagon bumper yesterday. Too bad I had to return my iPhone 4 that same morning (no, I had NO issues with the phone. I loved it. I had other reasons for needing to unload AT&T and the 2yr contract though).
Sucks, I have this case, 2 from Hong Kong coming, and the Pixelskin HD coming as well. And no iPhone to put them on. Maybe the 2011 iPhone will be the same dimensions and I'll get one again, who knows, so I'll hang on to them.
