Dismantling your iPod Touch is possible, but will void the warranty.
Like most of Apple's computers, laptops and mobile devices, the warranty on an iPod Touch will be voided if you dismantle it. Because the device uses a touchscreen, the screen itself is very delicate and costly to replace. However, it is possible for you to take apart your iPod Touch with simple tools. If your iPod Touch is giving you problems, take it to your local Apple store before attempting to dismantle it yourself.
Instructions
1. Hold your iPod Touch in one hand and a nail file or similar flat metal object in the other. Insert the file into the crevice along the top of your iPod Touch and carefully pry off the cover by applying pressure to the back case. Set the cover aside and lay the Touch on the table, open side up.
2. Pry out the battery in the center of the Touch with the file and set it aside. With the Phillips screwdriver, remove the screws at the bottom of the Touch, followed by the screws holding down a small cover next to the battery connections. Set the screws aside and take off the small cover.
3. Pull up the tab on the right corner of the device to reveal two screws, and remove those screws. Repeat this step on the tab on the left corner of the iPod Touch. Remove the remaining screws on both sides, leaving the Touch lying flat, as these final screws are all that's left to hold the screen in place. Remove the screen when finished.
