I have a spare iPhone 4 lying around with a broken screen, im going to get screen fixed and give it to the missus, i need to unlock it and actually have a gevey turbo sim but i believe with the gevey sim there are some methods and sequences you have to go through everytime you turn the phone on? is this true? as id rather an unlock method that wont leave her stuck with no phone etc

Any help would be appreciated

Your current baseband will determine unlockability. Please post it. The GEVEY SIM unlock is the only method that will work on an iPhone 4 that has been updated to 4.1 or later. However, it only works if the phone has never been updated to a stock 5.x. I you updated to 5.x without preserving the baseband, there is no way to unlock it at this time.
