Ok I see that sounds good, unfortunately we don't seem to have these ghost armour kiosks in the UK. Anything like that I would have to attempt to instal myself.
I have ordered a skin from bestskinsever which I believe is wet install, so I will attempt to do that myself. I may only put the back skin on though, if that goes well I will decide if I will also do the front.
I've done a few of the wet installs on some older phones. They can be quite forgiving when it comes to getting them aligned properly. Watch a few YouTube videos for some tips. Good luck!
