Apple has not yet release and iPod Touch 5th Generation. The latest addition to the iPod Touch was a White coloured model.
The difference between the Iphone 4 and the iPod Touch is that the iPhone is techincally a iPod, but with phoning capabilities. Also, the iPhone 4 can use FaceTime, a app that use video calling. Also, the newest iPod has FaceTime too. So, both the iPhone and the iPod are both the same.
It's just white and a 64GB model
The 32GB has more memory than the 8GB.
no because the ipod touch 4 is a newer version
There are multiple types of iPods with those generations. There is the iPod Classic, the iPod Touch, the iPod Nano, and the iPod Shuffle. All of those types of iPods have a third and fourth generation, but you can compare the one you choose on Apple.com.
yes the 3rd gen is shorter but wider, fater and heavier
No, you cannot. The graphics are too high for the iPod touch 2g. Guess you have to buy a new one Actually it plays just fine on my 2g 16g iPod touch, I have it both on my 2g touch and my iPhone 4 and i notice no difference in gameplay whatsoever(only difference is iPhone 4 can multitask while playing it)
