hi guys/gals

i know you've probably heard this a million times before buti recently had my iphone 3gs unlocked and was running version 5.0.1 ,when the phone came back from being unlocked it was running version 4.1,is it ok for me to update thtu itunes to 5.0.1? because ive heard if you do the phone will lock itself back to its original carrier is this true?any advice would be appreciated

the phone will lock itself to the original carrier when you update to any firmware, so you would need to use tools such as pwnage tool to preserve the baseband and upgrade using a custom firmware then use ultrasn0w once the firmware is supported. Not sure if 5.0.1 is yet but never restore to a stock ipsw unless you want to use the carrier its locked to
