Every now and then we see the TouchID on the back, then is under the display, then is gone in favour of FaceID. The latest rumor seems to confirm FaceID since it is written on the firmware, so I wonder if the images leaked with a hole on the back are referred to inductive charging.
Last year we had less rumours, I remember we read about the home button going away (I mean the physical one) but there were also rumors about TouchID embedded into the display, which proved wrong.
So some of the stuff we read may be completely wrong, as in the past.
I don't think so.
What happen now if you start the upgrade program with 6s and then want to switch to 7+?
I think it is possible, you end up paying more each month, but that's it.
The only problem I see is availability, many folks who bought iPhone 7 in September may not be able to upgrade before October or November and lose a month.
The upgrade program is not yet available in my country but I really hope they'll launch it in September for the new iPhone.
If they rise the price of iPhone 8 the upgrade program will become even more popular
