Who here is going to try a new bumper instead of a case for their new iPhone 4, once they get it? I think the white iPhone looks cool with a black bumper as shown in some pics, but I really want to see a black iPhone with a white bumper. I think the bumper is cool because it will protect the phone, but it won't hide the design. $30 for them seems excessive though. But I'm not sure how well it will actually protect the phone, now that I think about it. I think it's just for looks. What color iPhone are you getting, and what color bumper will you be putting on it, if any?
