Turning Your iPod Touch into a Phone

I always thought this was technically possible. Use your iPod Touch to make phone calls via the internet (with a mic attachment, of course). So I raved at the news that Truphone, a free app!, can do just that.

Here's an excerpt from their website:

The new Truphone for the iPod Touch application works on the 2nd generation iPod Touch and enables you to make free calls to other Truphone or Google Talk users, and cheap international calls to landlines and mobiles, from any Wi-Fi zone, using your iPod Touch's internet connection and a headphone with mic, or mic adapter.

Only problem is that I've got a first gen iPod Touch. But if you've got a second gen iPod touch, go ahead, read the full story.
