Nettalk (free voip to U.S. and Canada)
netTALK for iPhone, iPod touch, and iPad on the iTunes App Store
Works great over 3G/wifi and its free. They say you can call abroad back to the states over wifi which is a plus for travelers that want to call home.

I use netTALK during the day sometimes. The quality isn't crystal clear, but that's totally fine given that I can make free calls to anyone during the day. The only issues that I've run across is that the recipient doesn't know it's you calling from the Caller ID, but that's fine as well.
