Just like last year’s iPhone 5S and 5C, there have been numerous parts floating around that may or may not be (but probably are) the iPhone 6. The latest comes from French Apple blog iGen, which has posted shots of what appears to the two new iPhone 6 variations, right next to last year’s iPhone 5S. Those are depicted as engineering prototypes on what iGen claims is Foxconn’s internal software, thanks to one of its sources.

French Apple website IGen.fr (Google Translate) has shared a variety of new details about Apple’s upcoming iPhone 6, including dimensions for each model, info about the protruding camera ring on the rear of both devices, and more. The photos appear to be of internal information residing in a Foxconn factory, as the 5.5-inch iPhone 6 and 4.7-inch iPhone 6 carry code names of N56 and N61, respectively. The information states that the final version of the 5.5-inch iPhone 6 will measure 158 mm long, 78 mm wide, and 7.1 mm thick (7.7 with the protruding camera), weighing 184.6 grams, or 6.5 ounces. Also spotted is information for a first prototype, which retained the same length and width but was 7.0 mm thick and weighed 168.5 grams, or 5.9 ounces.
