I used these guys to unlock a Blackberry.
They gave me several codes to try.
If you have had your phone for 3 months or more, most cell companies will give you the codes if you tell them that you are taking it overseas and need to use a local sim card.
You only get so many tries to unlock, so you want to make sure to do it right.
