i believe dry cleaners have a machine in whereby they can remove iron on lettering - not 100% sure though. otherwise just get a iron on sticker which is the same colour as your jersey or print it out, and stick over the top.

alternately, depending on how old your jersey is/how much you wash it, the letters often start cracking and/or peeling. you could encourage this on the letter you want to get rid of
