About a week ago, we checked out new leaked photos that came to corroborate rumors of an iPhone 7 Plus with dual camera and Smart Connector.
Because today the NWE released photos obtained in China showing the alleged three models of the "IPhone 7" Normal, Plus and a new “Pro” side by side:

The backs start to become “old acquaintances” of ours:

As some rumors of old times pointed out, only the “iPhone 7 Pro” would have a double camera at the rear and also what appears to be the Smart Connector at its bottom. And that's just what we can see from the outside, of course; maybe there are still other differences internally, such as more RAM and / or a greater storage capacity (256GB?).
But do you know the most curious part of today's photos? THE "S" under the name “iPhone” on the back. That, to me, makes no sense at all
