If your screen is significantly cracked to the left edge, abandon this entire setup, prepare yourself for a 5-6 hour repair, expect a lot of patience, a lot of cursing and some good old American ingenuity. The suction cup and picks will not work. You have to carefully crack the glass yourself (w/out damaging the panel underneath and carefully pull it apart from the inside to the outside edges. Use a hairdryer to soften the glue under the cracked panel along the edges. Then use an exacto-knife to separate the pieces of the glued panel from the frame body, all the way around the device. Watch out for the home button ribbon connector when using the exacto-knife. There will be glue residue left over, carefully apply some goo-gone to a small area of a paper towel and wipe gently around the frame body to loosen the glue. Then use the plastic spudger tool to scrape off the excess glue.

The iPad repair is VERY difficult. If you are a working adult, hire a pro. This is not for the faint of heart.
