There’s a real tutorial video from blogger TechRax that shows how you can drill a headphone jack into your iPhone 7.
Don’t do this. Honestly, you should be smarter than this and not actually have to be told, but, yes, some people might actually try this. It doesn’t work.
You will however, end up with a hole in your phone and your iPhone7 probably will eventually have some major problems and stop working.
So, again, please…don’t take the drill to your iPhone 7.
