It depends upon what type of unlock you did previously to your iPhone 3GS. In most of the cases, Upgrading an iOS would relock the iPhone. So, You have to unlock your iPhone again. But nothing to worry. You can unlock your iPhone 3GS safer and easier using remote unlocking service. You can get the remote unlocking service for an iPhone 3GS from www.Mobile-Unlocker.Com at affordable cost with free unlocking instructions. This method of unlocking doesn't require a jailbreak too. Good luck mate.
