It has built in speaker, it's thinner and it has a brighter screen.
i have 2 ipod touch 4g (8gb/32gb)
no
there isn't a 5th generation iPod touch
No you can not ring off a ipod touch 2nd gen
You cant replace the battery.
the same as the 2 gen on 3.1.2
yes but you have to pay a little extra
YES! Shazam works on Ipod Touch 2nd Gen. I called the Apple store personally yesterday. It works on 2nd Gen. only, not the 1st Ipod Touch. The Ipod Touch 2nd Gen. has a built-in speaker where the 1st Ipod Touch does not have the speaker. For Shazam to work you will have to buy a mic to plug into it to record the sound. You can call the Apple store at 800-MY-APPLE and find out for yourself if you like.
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.
Apple has already made a 3rd gen ipod touch.
Yes, the iPod touch has always had Safari on it.
Anyone who has a ipod touch 4th gen.
