All of those last codes do not work. Love people who take them but don't tell us which ones they took. I tried them all. Would like to get this if someone can pm me directly a code so it doesn't disappear before I get it.
pretty sure they are wet. I've done a bunch of wet installs and they work well. best practice (IMO) is to do it in a bathroom with the shower running hot. This keeps the moisture in the air and prevents dust floating around and landing in between your skin and iPhone. I also use a small sprayer (a bit larger than a chapstick) that I got a while back to spray the soapy water on vs using the bowl method. And some painter's tape on the edge of a credit card or driver's license to smooth out the bubbles.
