I forgot the pword to my ipod touch and I cant restore it.?

I dont have itunes, because I used a friends itunes a long time ago. I just got my ipod back from a guy who had to use it for a case. He hasnt replied to the email i asked what my pword was. And now ive disbaled it forever until i get it to itunes. What should i do? Is there a number I can call so it will make it so its unlocked?
