Jailbroken iphone restoring it to 5.1 tiny umbrella?

Hi if anyone could help me with this i would be very grateful. I had a jailbroken phone but i stupidly tried to update it to iOS6 using iTunes. I can now not activate it because it isn't the original sim carrier. I have downloaded tinyumbrella and i pretty much know what to do, change the setting to set hosts to cydia on exit but tinyumbrella won't let me check it because it's greyed out. How do i check it? A quick reply would be very much appreciated!
