Ok, after a long research I narrow the search down to these two cases: 1. The Quattro-T4 Glass touch-thru case by IvySkin Description from IvySkin's website: Announcing the 2.0 version of the most award winning iPhone case! We are always looking for new and exciting ways to improve the quality of our products. Curious about whats new in Quattro-T4?

The Defender clear membrane case by Otterbox Description from Otterbox's website: The OtterBox Defender Series for iPhone 3G / 3GS offers stylish and sophisticated protection in 3 layers. First, a thin, clear membrane covers your Touch Screen to help prevent scratches and dings. Second is a hard, strong Polycarbonate skeleton that surrounds your device. Wrapped around all of this is a Silicone skin that absorbs bump and shock.

I like the IvySkin slim design and all the things they compacted into this case but I need to know what other people think... Let me know!
