T-Mobile has announced $10/month VoIP (Voice over IP) phone service. It's an interesting twist on VoIP, with the company leveraging portions of its wireless cellular network to reduce the cost of providing the service. It is, however, a landline service, and you have to have T-Mobile cell service AND a broadband connection at your home. But you can't beat the price, which looks pretty good compared to an average $40-$50 per month cost of old-fashioned copper-based local/long distance bundles.
