No, you can sell your iTouch 2G and purchuse a newer iTouch
2G means Second Generation. So it is a Second Generation iTouch.
Absolutely 2g+ although if you don't have a 4g iPod Touch you need to get headphones with a built in mic to actually talk.
no it doesn't. i have an itouch 4g and it doesn't have soundhound. hope that helps :)
No.
the 8th
no only an iphone
no, 4g is thinner
about $2g/$4g
ipod touch 2g-4g
But what?
No there is not. As of now if you would like an iTouch that looks like a second generation iTouch you should get a second generation iTouch.
1G is flat 2G is horizontal 3G is vertical 4G is overhead 5G is pipe
