LTD Tools have created a new iPhone 3G and 3G S case made of stainless steel. The stainless steel iPhone case comes with a protective hinged lid, several vents and access to parts of the screen allowing you to use the iPhone with or without the lid open.
Silicon pads are built in to the case protecting the iPhone from bumps and scrapes and gaps are cut out around the buttons to allow access to volume, power, lock button and camera.
It's quite a beast of a case and will certainly protect your iPhone from getting damaged.
The iPhone case is priced at $95 and is available from LTD Tools.
