    Default Unlock 3gs
    Hi i am having trouble unlocking a iphone 3gs on 3.1 fm 5.11.07 i have tried blacksnow and it installed but i tried a tmobile sim card at my wifes work and it kept asking for pin.. the guys whos phone it was knew nothing about the phone (not even if it was tmobile prepaid or regular account) so im not sure if it worked or if i need a pin for that sim (im asking cause i sold the phone on ebay and want to make sure the buyer will be able to use his sim) any help would be appreciated on whether i used the right unlock or should i upgrade my f/m.. its been a while but i think i used blackra1n for the j/b thanks

    You have to restore to 3.1.2 for Blacksn0w to work properly.
