The last four came from a Radio Shack book, but I can't tell you how to use  
them (except NOT to use them).  They are the famous "Blue-Box" tones generated  
by another one of Steve Wozniak's electronic inventions (or so urban legend has  
it).  I guess Steve Jobs has finally outdone The Woz's Blue-box with his  
Black-box :-)
