I have an iPhone 6s, and I cracked my screen. It is under AT&T and AT&T Next. I'm not planning on upgrading any time soon, but I want to replace the screen and would rather replace it myself with an OEM part than pay $120 for the same thing. I have 2 questions: 1.) I've been told that OEM parts are the exact same thing as the original parts, so does it have all of the markings and stuff? And 2.) Would AT&T check or even care? I know that there are serial numbers on most parts in the iPhone and I assume it's matching for every part, so I was wondering if they check that and if they would care if they found out that I opened it and replaced it. Thanks.
