The iPhone 4 may have just been announced, but there are already some great options for cases to protect your phone. Uncommon (you might recognize the brand from its awesome iPhone cases benefiting earthquake relief in Haiti) has introduced a line of customizable cases for iPhone 4 including the Trooper, Gallery, and Loop cases.The Gallery case features a completely customizable hard back; upload an image while ordering, or select one of the predesigned cases. Your phone's frame and screen are protected by an elastic bumper. The flexible Trooper case is a one-piece, slim, shock-absorbing case, also customizable with artwork of your choosing. Finally, Uncommon's Loop case is a simple, flexible, frame-style iPhone case that protects the edges and glass of your iPhone while keeping the front and back glass exposed.
