Accessory maker Case-Mate has published images depicting cases for an alleged iPhone 5 design, reports note. The images are consistent with cases being produced in Asia, showing a phone with a flat back, tapered edges and elongated volume buttons instead of circular ones. Case-Mate's images also imply an aluminum back instead of glass. On one of the company's webpages, it claims to have "inside resources" on the next iPhone's specifications and launch date.
