aren't blue boxes(ahem) illegal? and I'm confused. how do they work. i mean, i know that they allow you to make free phone calls and stuff but, other than that, how do they work? btw. i've got one of those little things from RShack that you put up to the phone to make a call and it produces the tones(that's all it does). would this help?
