This past weekend, an image claiming to show a bin of boxes for Apple’s upcoming lower-cost, plastic iPhone emerged with “iPhone 5C” as the purported product name. However, earlier today, the image was claimed to be debunked due to some minor inconsistencies and image distortion.

It’s unclear what the “C” in “5C” stands for, but we can discern from the 5 that the plastic iPhone could be a cheaper version of the IPhone 5, complete with plastic, colors, and perhaps slower processing speeds.
