What iPhone model is shown in Apple's Recycling video? In Apple's most recent event, they highlighted their environmentally-friendly products. One of their videos sported a robot named Liam, who would disassemble iPhones once they were in need of recycling.

However, in the video I couldn't place the iPhone shown on the disassembly line. I've included an image below. Can somebody identify it? Or is it not an iPhone in the current lineup, something different or...dare I say...new?

Looks like it has a flush camera lens, which is something the newer models don't have. That's what's confusing me.

Link to the video is right here, at the bottom of the page.
Judging by the guts of it, the size, and the finish, I am going to say that this is an
iPhone 6
It's too big and rounded to be a 5/5S series or earlier.  Assuming that it's not the iPhone 7 (which hasn't even hit the prototype phase), we can narrow it down to a iPhone 6 or 6S.  There is one slight difference between the two:

In our little video we see that it has only the iPhone name on it:

So, that's why I say it's an
iPhone 6
