Unlocking phones (correct post this time!)

[Columbine]

Hi There,

Sorry, I suspect this has been asked dozens of times already, but has anyone had any luck unlocking softbank phones?

I have an 812sh, and I'd be interested to know if anyone else has managed to unlock it. I hear I might need to buy a special sim card to do so, has anyone else bought one of them, did it work and if so, where from?

Thanks!
