A new report emerged on Thursday that resurrects earlier rumors of a larger display on the upcoming iPhone 5, as well as a full circle return to the sleek metal case of days past. The Apple aficionados at 9to5 Mac claim to have a solid source at Foxconn, the Chinese manufacturer responsible for building the iPhone, who claims iPhone 5 production is getting under way. Considering the next iPhone is expected to launch in June, this would certainly make sense. The mole reiterates earlier rumors that the iPhone 5 features two main design changes compared to the iPhone 4: a larger display and a metal case back. Other than that, the source suggests that the iPhone 5 looks much like the current model. Some have argued that the metal case on Apple’s original iPhone caused signal attenuation issues, but now that the company’s unique new external antenna design has been sprinkled with a dash of reality distortion, antenna attenuation and dropped calls are features, not bugs. Should it choose to continue utilizing the current design, Apple could use any materials it wants since the user’s hand does the attenuating, not the case.

Note that the image above shows a metal-look case back accessory for the iPhone 4, not a device claimed to be the iPhone 5.
