I came across this case for the First Gen iPhone last night, it looks great! It's a hard case with some rubber accents for easier gripping. What really interested me was the soft rubber on the inside that acts as a shock absorber and helps to protect the phone's surface from scratches.
I went ahead and ordered it, should be here in a few days. I was wondering if anyone has it now, and what your opinions are so far. If anyone is interested, you can order it from iSkin:
