I want to learn about the methods of recycling and Amazon / Google search didn't give me good results. Amazon gives me "how to" recycle which is not what I want. I want to learn in detail "how it is" recycled. Google gave me some high level article but I want to go deeper...
Previously iPhone UDID was 40 characters. Now for iPhone Xs, Xr, Xs Max, they change to 20 characters with hyphen. It looks like it is following some sort of pattern. Does anyone know anything about it?
We have several Xs and they all start with 00008020-
