Apple's new Bumper cases for the iPhone 4 look pretty and vibrant up close but only protect the metal bezel around the iPhone 4. From the looks of it, the Bumper has a great lay-on-the-table design on both sides to help keep that glass from sticking out. The Bumper cases will be on sale this month with a price tag of $29.
As you can see, the back part of the iPhone 4 is fully naked. The Bumper case will be a perfect match with a back film protector to ensure some extra protection from scratches if any.
