Ipod nano 6 gen does not have a built in speaker only nano 5 does
yes it does and it is called an ipod classic. it is just fatter and exactly he same
Try charging your Ipod.
no, they will only work with the nano, as the nano is quite a bit smaller than other ipods and mp3 players. If you bought a speaker for an ipod touch, it would also work with the nano.
No. go to "ipod games under itunes
no, it is also in a ipod nano 6gen!
Neither works better, but i like the iPod nano third generation. It is alot smaller, but still does video.
No the touch has its own updates. =]
