The New Aluminum Bumper Frame Case  for the iPhone 4 is now here and ready for you to pre-order!

First of all, the  ergonomic shape is very sleek, light, and of course, beautiful. Thats really all you need to know, but heres more:

Despite its minimalist appearance, the bumper is CNC machined from a solid block of aircraft grade aluminum. In other words, its strong and light(22 grams)!
A CNC on/off button is designed into the case to complete the clean lines.

 
Next, the finish of the bumper  is anodized to create a hard protective coating in brilliant colors. Yes, black is a color. We love anodized black.

The inside of the bumper is lined with a very high tech shock absorbing material that reduces the G-forces of an impact. 

 

It also creates a non-conductive barrier to help maintain the iPhones antenna signal strength.
