Skype

Yes. If you can get on the Internet and the signal is fairly strong/robust, then Skype really doesn't care about where you are vs. where you're calling, other than rates adjust for Skype calls to landlines (instead of calling Skype to Skype). You can check rates from where you are to where you want to call on the Skype site. But if you are connecting to someone also running Skype (so you're not calling them on their home phone), it will cost nothing.

 

Exactly! You can call North America from Europe or elsewhere in the same manner as making a skype call locally.

If you have the latest generation of ipod touch as you say (3rd gen), it will have come with a mic built into the headphones. You don't need to buy anything else.

 

I do not think the 3rd gen has a mic. Correct me if I am wrong.

 

8 32 64

The 8 gig has no mic. (though Apple and others sell 'ear buds with mic') The 32 + 64 do.

 

Yes, as the previous poster said. I have the 32 and the 64 also comes with a mic.

 

Exactly. Skype to Skype is free and you pay (very little) if you use Skype to call a landline. At present, I'm in the Caucasus, and I use Skype most evenings to call Skype accounts and landlines in western Europe. It is very easy to use and exceedingly reasonable. Mic and headphones are better than talking to the screen - I got a good quality Logitech set. However, the quality of the calls can vary (depending on the quality and stability of the internet connection).

Cheers and good luck
