Hi, I lent my grandson my iphone 12 and I got it back with a broken screen and a broken back glass. I have another iphone 12 for parts. I was going to swap out the screen and the back glass. My question is do I have to remove all these parts as described above or c an I just plug the new screen in ? Second question my iphone has a Qlink wireless SIM card in it and it works perfect. The same SIM card will not work in my other iphone that being said would it be easier to somehow take my other iphone and use the parts from my broken one so the SIM card would work in it? I don't know what it would entail to do such a thing but if you would possibly know what I would have to do to make this happen please let me know... Otherwise I will take the screen and back glass and continue to install them on my own phone. also which procedure would be easier to do?? Kudos to you on this article I followed it to the letter and everything worked perfect I removed the screen without any problems. GREAT ARTICLE! Thanks Jeffrey
