Sold it on eBay but the customer didn't want it so he sent it back. I took it apart and it's been setting apart in its box for three years and I finally decided to fix it.
I just finished a certificate course on iDevice repair from the Cleveland Institute of electronics so this was my first actual device repair. I decided that I wanted to make a little extra money while I'm pursuing my degree in electronics so it went great!
This will work on any iDevice when you have to remove the adhesive, I use a spray silicone lubricant and spray it on the rag then just rubbed over the adhesive material and it came right off with no effort at all
