Yes. The second and third generation iPod Touch are the same size. Ipod Touch 4G or fourth generation, is thinner and weighs less.
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.
Both an iPad and a fourth generation iPod Touch can use the same Messages app, so yes.
the 3rd generation of ipod touch 8GB is basically the same as the 2nd generation ipod touch 8GB, if you want a real 3rd generation ipod touch you should go and either the 32GB or the 64GB version
Yes. iPod touch 3rd generation is just a 2nd generation iPod touch that's faster and includes support for newer operating systems.
Yes, if they are the same generation.
No, I've seen both of them and they are exactly the same size and shape.
No 2.2 is the software 2nd generation is a whole nother ipod touch version which is slimmer and has an internal speaker not like the 1st gen.
The ipod touch fourth generation has been out for just about two years. It came out September 8 2010.
No, they are not the same. The 3rd generation 8 gigabyte iPod Touch should have a built-in microphone. The 2nd generation does not have a built-in microphone.
Yes you can use the 4th generation for the 3rd because they are exactly the same but the 4th generation has a camera
The 3rd generation and 2nd generation iPod Touch are the same size and shape. Neither is skinnier or thicker than the other.
