Replacing glass on iPod Nano 4th generation
Daughter dropped her iPod and the front glass shattered. The iPod worked, but the glass was broken into dozens of pieces.
The repair only took a few minutes. I read the instructions on iFixit, followed them, and had the glass replaced in a few minutes.
Take your time, don't get in a hurry, be very careful removing the cover plate and the tiny screws. ( the screws are set at an angle, note the direction of the screws.. they are not straight into the body of the iPod..)
iFixit has great tools for all kinds of repairs. Use the proper tools and the job goes much better...!!!
