Here is how you will take apart the Nano iPod
There are no screws on the outside so it looks like impossible to take apart, the way to do it is, to heat up the screen with a hair blower or any other heat source, to soften the glue. You have to watch not to heat it up too much, not to break the screen, or any other part in the Nano.
Keep checking with your hands if its not getting too hot.
