Pamper your iPhone by getting them one (or all) of the Griffin/Otis James iPhone sleeves. Griffin Technology approached Otis James to collaborate on a line of accessories for the mass-produced Smartphone due to his expertise with fabric.
The cases are more of a luxury item for your phone than a protective covering. They are made of either linen, silk, cotton or wool depending on what finish you choose, and they come in different plaid and checkered designs. There is an added bonus added to each of the Griffin/Otis James iPhone sleeves that comes in the form of a small front pocket. This little pocket is able to neatly and efficiently store your earphones so you won't have to bunch them up in your jeans.
The sleeves will hold both the iPhone 4 and 5.
