Guess what! We've got another one of Krypton's flex case designs here. Today's design is called Black Groove and has a neat little white design (reminds me of DNA) on the back. I really like these Krypton flex cases. To find out why I like them so much head on over to our first Krypton flex case post to read the whole review. Basically they are silicone cases for your iPhone 3G/3GS that are built well and look great! Check out more pictures after the jump!

You can win this case!
