I dropped my iPad 2 about 8 months ago. I have lived with clear box tape over it for all that time.
I had prevosaly done the digitizer on my iPhone 3GS t,hre or four times. This was much easier. The videos from infix help other than not actually using broken digitizer.
Just be sure you get all the little pieces. Mine took a reboot to work, when I initaly started it the back light on the LCD did not come on, used a flash light to see buttons to reboot. After that perfect.
