Does anyone know a good spanish-english translation program for my pocket pc?

I would like to download a program for my pocket pc that you can either speak or type in a spanish phrase into it and it would translate it to english or vice versa. I was hoping for a freeware program but I would entertain purchasing one if I could try it out first. Any suggetions?|||try www.freetranslation.com. We use it in our office often.
