Alleged photo of the iPhone 7 rear pops up again, depicting subtle design reworks
We can see the larger camera lens on the back, something that has appeared in previously leaked sketches and photos, but this time it seems a tad flusher with the surface, so we don't know which one would turn out to be the real deal in the end. We can also see that the old antenna line strips that have been present on the iPhone 6 and 6s are gone from the back, and have been moved to a location on the side just under each corner.
On a side note, Apple could be adding waterproofing certification to the iPhone 7, according to latest rumors, so that might have been one of the reasons for moving the antenna lines, but that's again something that can't be judged from such a photo. It would be a great way to move those 80 million pending upgrades into the iPhone 7, though, while keeping the watershed redesign moment for next year's edition.
