Will be interested in how you get on with the screen removal.
The headphone socket has gone in my ipad, just £3 for a genuine replacement part, modular just plugs in so no soldering, BUT .........
Need to remove the front screen.
Plenty of Youtube videos, heat it up, pry it off, seems pretty simple. Even bought a pry tool and a bunch of plectrums.
But then I lost nerve and decided I'd pay a repair company. But most didn't want to go near it, and those that did wanted a lot more than I was expecting, about the same as replacing a broken screen.
I eventually asked why it was so expensive and they explained that it is very common to break the screen when trying to remove it. Not a problem usually as most of the time they are replacing a broken screen anyway. But if replacing the headphone socket they need to factor in the possibility of breaking the screen.
Cheers,
