Most likely your iPhone was jailbroken to unlock it so it would work with your current carrier, and upgrading iOS has now removed that jailbreak and your iPhone has locked back to the original carrier. You will need to contact the carrier to whom the iPhone is locked and ask if can be officially unlocked, which after jailbreaking may well not be possible.
