The iPod Touch doesn't come with call or text features as it is not a phone. However, there are many apps available that allow you to text and call for free using wifi.
There are apps that allow you to dial phone numbers
Yes actually you can ipod are so great everyone should have one i have one but texting to a phone is good and you can talk to your friends by texting

it depends if you like to talk alot or if you like just the apps. if you like to talk, then iphone, if you like the apps, then itouch. i hope this was helpfull ;)
Go to http://www.google.com/talk on safari on your ipod touch. :D Enjoy!
tell them everyone has it, it worked for me.
if you have to talk into it then you cant because an ipod doesnt have a microphone!
iMessage for ios5 or text me which you can buy in the app store
As far as i know you can only talk if you plug in a microphone. I hope that answered your question! 
You can talk to him over instagram for iPhone and iPod touch or twitter or Facebook
surprisingly, yes! but its kinda complicated. first, you get a mic off amazon, then you install whistle phone off the appstore, then dial a number and talk. you can also txt on ipod touch. just search textfree on appstore.
