Wireless carriers want crackdown on cell phone boosters

"This is 'Magic' and this is 'Jack'," the little girl says in the video ad, holding her two cute puppy dogs up to the camera. The girl's father, magicJack inventor Dan Borislow, then asks her, "Kylie, did you know that your dad is going to let everybody try a magicJack in the whole country for free?"

Free for 30 days, that is. magicJack is a popular service comparable to VoIP, except that after you hook its app into a USB port on your broadband connected computer, you plug the USB gadget to the RJ11 slot in your telephone. The cost: $39.95 for the initial year and $19.95 for subsequent years to make local and long distance phone calls.
