I have been hearing about this for a while now, but what exactly is it? Also where can I find one that works? I google'd it, but there where many, many different ones that popped up. I doubt there are that many working generators. Thanks for the help.
Edit: I google'd Chinese iTunes code gen. and it came up that you can buy these too. If anyone has gotten one and it works please tell me where. I am really interested in this now.
