If I may butt in to add on ac3mark's reply.
Facebook has 2 billion monthly users, so when ever you try to deal with Facebook you must remember that you are dealing with a machine, a system so one must think in terms of an automated system, not like a person to another person.
I don't think that Facebook will not let correct your typo error. You should have corrected it by deleting the account and creating a new one without any mistakes before you started collecting 3,000 friends. Since you must always use your real full name, if I were Facebook, I would ask why you went on with an error in your name. It's not logical.
P.S. It's impossible to have 3,000 true friends
on a social network.
What do you think?
