iPhone 4 Cases: Bumpers
Bumper cases cover only the sides of your iPhone 4, leaving its screen and back exposed. Bumpers offer protection only against drops, and even then only if the phone lands on a corner or edge. However, if you've experienced reception issues due to the iPhone 4's external-antenna design, a bumper case should improve reception by preventing your skin from bridging two or more antennas.
