You mean you updated the firmware and now the phone is locked?
Can you provide more information on the model and firmware of your iPhone?
All you have to do is jailbreak then unlock so you can use it with your current carrier.
See this matrix along with the tutorials on how to unlock your phone. Let me know if you need additional help..
