You need to be careful with that; updating your firmware will undo any jailbreaks or unlocks you’ve currently got on your iPhone.
Answernode has free software to fix it (Mac and Windows, no Linux support yet though) – so I’d use that. It hasn’t happened to me personally, but my partner used it when he got my old 3GS and wanted to unlock it.
