I wasn't aware that the 3G didn't have accessibility, but they've trumpeted it a lot over the last few years so I have a hard time thinking they would just give it up.
I mean you could just make a setting that ignores whether someone is "looking" at the phone. It would make it a little less secure but at least it would still work.
I have a very hard time believing the rumors that they took touch ID out at the last moment. Maybe when people do teardowns will see some empty space but I figured that something they would've had to lock down early in the year.
I've got to admit I'll miss touch ID. I wonder if it'll ever come back if they figure out a way to get that sensor-under-the-screen thing going, or at this point do they just decide Face ID is good enough and go forward with it alone?
