No.
You can all you need it the apple headset and speaker (if 3g -)Because there is a new app called iCall which lets you call to USA and CANADA free for the ipod 4g which comes with a facetime speaker.(requires headset and speakers.)
No, you cannot call on the iPod Touch. The recent iPod Touch that came out in September 2010 can call people that have FaceTime such as iPhone costumers. But unless you have the new iPod Touch that has a camera and FaceTime, you cannot call other people.

ipod touch
Not unless you have a 4 generation iPod which had a camera
Lets say you have 150 songs you will be able to hold around 160 apps which is the limit of the ipod touch
The built-in Music app views and plays music placed on your iPod Touch by iTunes. On unmodified iPod Touches, the Music app icon is orange and has a note symbol.
there actually is no ipod app that lets you call without wifi because you need the wifi to get it where it needs to go.
Lets you play games and listen to music.
Sadly, there is no such app that allows you to do this.
For fourth-generation iPods (iPod Touch), there are four ways to communicate with other people with an iPod:You have the iMessage application already on your iPod when you get it that allows you to send messages, videos, and pictures to other people that have an iPod Touch.The next is email, you are able to access your email account on your iPod and so email your friends.You can also text people with the app Text Free. It allows you to text with your iPod to people with phones capable of texting and other people with iPods that have that app too.Last, and most useful, is Facetime. You have to have a fourth-generation because they have to have cameras. Facetime is a video calling application that lets you call people that also have an iPod (fourth generation) or another apple product that is camera enabled, such as a Macbook.
You need to download an app called ispoof. It lets you call someone as someone else, but dont try to trick to your parents :)
