How do you tell if my 350 is gen I or gen II?

Go to settings then click general settings then it will tell you.

Gen x or y are different groups of people that where born at a certin time.Hope this helps

On your ipod touch box, (you should have received) like the one it came with, it should tell you. So, just check on there, and also read the back and everything! And if you can't find it...

generation

One way that I check, is that I download battery LED from the app store. At the top, it should say what gen.
