The iPhone 3G launched in July 2008 and in the past year tens of millions of units have been purchased. The 3G is still for sale on AT&T for $99 on contract. This is perfect for those who do not need some of the iPhone 3G S’s features such as the digital compass.
The Gradation Case by Gogo for the iPhone 3G is quite nice. I could hardly notice I had a case on since it weighs less than an ounce and only makes the iPhone 1 mm thicker. The back has a cutout around the Apple logo so you can see it. It is very easy to snap the phone into the case but a little difficult to snap it back out. As far as protection for the case it seems to offer very good protection on the back. There is very minimal protection on the front, but it does come with a screen guard which should help. Overall I would recommend the case to someone looking for a hard case that wants to protect the back of the device.
