if you jailbreak it the mic can support anything
get Skype, or get the new iPod Touch with Facetime, or get the Textfree Unlimited App with Voice. They all work.
Try Skype or Fring, both those work.
Yes, But if you want to do video chat, you have to have a fourth generation or higher. For additional information, visit Apple's website.
Yes, the app textplus was made for the iPod touch. If it is on the Appstore for Apple, IT WILL WORK ON AN IPOD TOUCH.
No. But if you have an iPod touch you can download VOIP applications(voice over internet protocal) such as Talkatone(free), textfree with voice(semi-free), or skype(free skype to skype but needs paid subscription or credit for other phones) and use the app to make the calls if you have a 2nd or 3rd generation ipod(plus the iphone headset with mic) or a 4th generation ipod touch(has built in mic). It will still not work as well as a cell phone as it is really buggy, but if you primarily just text and use the phone occassionally than it will work well.
You touch it.
Yes it's called call.net or something like that, but you need WiFi and a microphone. Skype might also work for you with WiFi and a mike.

No, you do not need a Mac to have a computer work with your iPod Touch. You can use any PC that has the ability to run iTunes to work with your iPod Touch.

You touch it with your finger...
Yes, they do work with the iPod Touch 3rd Generation. The earphones should have came with the purchase of the iPod itself. But yes they do work.
