unlocking nokia 3100

I have tried to unlock my nokia 3100; first by accessing nokiafre.org but i couldn't find country Brazil on the list. Then I downloaded 2 programs to generate codes: Cyber_5.4 and nokia free_calc. It failed 3 times already!!!. I think i used the default GEN (33552) but now i am afraid of trying GEN new griffin (34144). What should I do now? Any help please :-? Thanks a lot
