No new content again? I’m afraid so. Why? Because I was voiding a warranty:
Somebody needed the power button in their iPhone 4S replaced and figured I was the man for the job. They were right. I replaced the button and the phone powered up again. Of course it doesn’t boot up, but that part wasn’t my fault as it wasn’t actually booting up beforehand (and since the power button stayed in the stuck down position the thinking was that it was just turning off, due to the power button being held in, immediately after boot).
I will say that working on the iPhone 4S is pretty easy.
