hi guys,

a little while ago i ran into an article on phone phreaking, and i would really like to know more about it. not about getting a scanner and listening into a phonecall, i don't care, but the so called "fingerhacking". does anyone know of any articles/howto's/tutorials about this subject? i've googled on the subject for about half an hour now and still haven't found anything usefull

thanks in advance
