yeh, it does
Yes on the iPod Touch but the info still might be on your computer
No
Well for starters all I know at the moment is a 4th generation has both front and back camera's.
look in the back of ipod
yes check the back of it
If it's the iPod touch 4th Generation, there is a front and back camera.
You cannot take pictures with the iPod Touch. Yes. It depends on what generation the iPod Touch is.
The screen size is exactly the same. But, the back of the 4th generation is flatter, so if it is placed on a surface it won't wobble.
Yes.
The 2nd generation has a chrome colored trim around the front. The back of the iPod touch is also curved. The area for the wifi is shaped as an oval. There are also volume buttons on the side. I hope this has helped. Addition by Techies: The best way to tell if you have a 2nd Generation vs a 1st is that the 2nd has speakers built in, where you don't have to plug in any earphones. It's also thinner then the 1st Generation.
There are different things for each iPod. I have the fourth generation, so I have a camera on mine. My friend has the third generation but does not have a camera. The other iPods are also thicker.
Newest Ipod (4th generation) has 2 camera's on the front and on the back
