Decided to stop by the Apple store in the mall I was shopping in today & noticed they had the Contour Showcase available for the iPhone 3G. I had the case for the 1st iPhone & I loved it so I had to go for this one.
Noticeable improvements such as thinner (not as bulky as original), the clip is nice & solid and the stand by/power button is concealed rather than exposed yet still accessable. It has a soft spot to access it. So far I'm pretty impressed with it since it's a pretty solid case. I'm very clumsy with my iPhone and couldn't stand dropping this one as I dropped my last one w/out a case and destroyed the screen.
Some pics for the curious.... Price was $35 btw.
