the main difference are the cameras
4th gen has a camera.
yes the 3rd gen is shorter but wider, fater and heavier
There are certain games that you cant get on the ipod 1st generation also you you cant update ipod 1st gen with the new softwares but with the 3rd gen you can carry on updating it.
The "generation" label refers to the version of hardware you have. iTunes will update the software on your iPod to the latest version. Gen 2 Ipod Touch also has volume buttons on the outside, as well as a speaker and the ability to use APPS from the Apple Store.
The 3rd gen. has more memory and you can get more games than the 2nd gen. because some games require the 3rd gen. and you can't buy them unless you have that generation.
Not much. The only big difference is that the 3rd generation has a better processor, so runs around 50% faster. Also, the 3rd generation iPod Touch is available in a 64GB version, and is also cheaper.
Go to settings then click general settings then it will tell you.
The difference between the Ipod Shuffle and a Ipod is that the shuffle has no screen and the Ipod Nano has however if you are looking forward to get an Ipod i would not go for them 2. I would strongly recommend you to get the new Ipod Touch 4th gen because the new Ipod Nano that has been released was not as good as people thought it was. It looked nothing like an Ipod Nano at all it just looked like the new ipod shuffle. But if you are getting an Ipod Touch you don't have to get the new one because there is hardly any difference except that the 4th Gen has a camera However make it right you cannot webcam.
The iPod touch 2nd gen is the newest one. It is thinner, and It has the app store. I believe it also has higher storage options.
i don't know someone tell me please
The 2nd Gen has a curved back, slightly longer battery life, external volume controls and an internal speaker.
