Over the last year we've literally seen a ton of bumper style cases come out for the iPhone 4, and while Apple's official Bumper case set the bar high with its quality and dedicated metal buttons, there hasn't been many bumper cases that changed the way we look at them until today. Graft Concepts has designed a totally new concept for bumper cases we all come to know with what they call the Leverage. I don't think I was wowed like this before when I first set my eyes on the Leverage. Graft Concepts wanted to bring iPhone 4 users a truly unique and fresh case without compromising the already beautiful good looks of the iPhone 4 itself. As we all know, looks aren't everything. So how does the Leverage fit amongst other similar offerings? Find out after the jump!
