Hi everyone, Jack45 helped me to get my unlock code by recommending me the Samsung Galaxy S Unlock Tool app which worked for me. I bought my Captivate already unlocked, I just want to know if I update the firmware, will the unlock code, I got using the app, still work? In other words, does Samsung change the codes every new firmware? I know they prevent the code extraction method but I don't know if they invalidate the codes. Thank you for your help.
