As you will notice when I tried to remove the battery adhesive I was able to get one side out completely but the other ripped off. If you end up getting both out completely then you should purchase replacement adhesive as seen here... http://www.amazon.com/gp/product/B00B...
You could also use the first set of steps performed in this video to replace only the screen. Replacement screen kits can be purchased here... http://shrsl.com/?~7ax4
