A batch of photos published on Monday show what are purported to be three different models of the "iPhone 7," including a "Pro," but with unlikely "S" markings on the back.
In the images, discovered on China's Weibo by NWE, a smaller device is labeled as the standard iPhone 7, while two bigger devices are identified as the "Plus" and "Pro." The latter pair appear to be identical until they're seen from behind, in which case only the "Pro" has a dual-lens camera and a Smart Connector.
A handful of rumors have suggested the possibility of a "Pro" model, but typically these have been sidelined given Apple's current model split and the lack of any consistent word on what would separate a Pro device. The dual-lens camera and Smart Connector have usually been attached to the Plus.
Casting doubt on the authenticity of the images are "S" markings. Apple has traditionally reserved that badge for its interim performance upgrades, and released the iPhone 6s and 6s Plus just last September — a different use of "S" would risk confusion.
