I have unlocked 2 iPhones before and 1 was upgraded to 2.2.1 and naturally was re-locked (was a mistake) So I downloaded the newer 2.2.1 version of quikpwn and it goes through the process and says it was successful but after the final re-boot it only comes up "Different SIM detected, Please reconnect to iTunes" Why can I not unlock this phone anymore? 
Version number is 2.2.1 (5H11)
