Rumors suggest Apple (AAPL) is working on not one but several new iPhone models gained steam this past weekend as images of purported next-generation “iPhone 5S” and “iPhone 6” parts were published on a French gadget blog. Nowhereelse.fr, which has published images of genuine parts from unreleased Apple devices in the past, recently published a pair of photos that it claims show internal speaker enclosures destined for two different upcoming iPhone models. The author of the post says he “found the photos while browsing the web,” though he does not indicate exactly where the images came from. He also notes that the names “iPhone 5S” and “iPhone 6″ are being used as placeholders, and the site does not claim knowledge of Apple’s naming scheme for its next-generation iPhone models. Both leaked photos can be viewed below.
