new iPod nano have voice recorder?

Just like the 4th, 5th, 6th, and now 7th generation ipod nanos, when you plug in supported headphones (with a microphone) a new 'app' shows up on the home screen: voice memos this allows you to record audio through the headphones mic. unfortunely, you will have to buy new headphones/earplugs to use this feature.

if you dont want to buy new headphones, you can find external mic's to use instead. the 3.5mm plug must have 4 pins to use the voice memo's feature.
