What Model & Generation do I have?
To find out what model & Generation iPod you have, all you have to do is refer to your original packaging where you should find it listed.
What Size is my iPod?
Find out the size of your iPod by selecting Main Menu > Settings > General > About, then select Capacity. (On some older models you’ll need to tap Settings > General > About). The number shown here will be just short of either 8, 16, 32 or 64GB.
On some models the capacity is engraved on the metal case near the bottom on the back.
If you are having problems identifying the generation or size of your iPod then please refer to the original packaging or connect it to iTunes.
