Yes, you have to jailbreak your phone to use Yellowsnow(the unlock). Just be sure not to use firmware 2.2.1 unless it comes from a mac user who made the firmware custom or you will not be able to unlock at all. You do not want your modem firmware to be over 2.28.00. It can be found under Settings--->General--->About inside of your phone.
