Vaja has added to its line of iPhone 4 accessories with the release of four new protective cases, including the ivolution Black Series, ivolution Top, ivolution Top SP, and ivolution Grip. All four cases are made from Vaja exclusive leather, and provide full access to the headphone jack and ring/silent button. With the exception to the ivolution Grip case, all other models also offer a flip-open design, which protects almost the entire iPhone when closed.
