The company behind the magicJack, the cheap Internet phone gadget that’s been heavily promoted on TV, has made a new version of the device that allows free calls from cellphones in the home, in a fashion that’s sure to draw protest from cellular carriers. The new magicJack uses, without permission, radio frequencies for which cellular carriers have paid billions of dollars for exclusive licenses. YMax, which is based in Palm Beach, Fla., said this week at the International Consumers Electronics Show that it plans to start selling the device in about four months for $40.
