Heat gun works well, get the edge hot and it peels easy. Tips- A single edge razor blade is IDEAL for the initial lifting of the glass. Have about a dozen guitar picks to leave in place while working your way around. Carefully open the lower right corner about 1/4 inch and un-peel the antenna from the back of the glass (heck they're 2 bucks, just get another in case).
Step11- I tore the antenna, still works though. Buy a new one for 2 bucks off amazon before repair just in case.
