Skype is going World Cup crazy by offering a promotion to help football fans the world over stay connected. Offering free landline calls in multiple countries (more on that in a second), U.S. residents will get a bit of extra love with free mobile calling for a month. Thirty countries are included in the promotion, and depending upon which country you call you will receive 60, 120, or unlimited free minutes of calling, so be sure to check out Skype’s blog for the full details.
