Since last wednesday a guy called Rodolfo Romero in Iquique Chile is hardware unlocking phones. So far he has unlocked 5 phones with only one getting bricked.

He is charging US$190 (Ch$100.000) for the Unlock, but that price includes a guarantee of a new iPhone if anything goes wrong while he does a Geohot Hardware Unlock on your phone.
