Before you updated to 5.1.1..... what iOS version and Baseband were you on?

I assume your using the correct sim as you didn't have problems with the upgrade(no request for activation )
Try taking out the sim card, wiping and replace... or try resetting all settings in Settings>General>Reset>Reset All Settings

Try once again. Question is, before the update, did you use Gevey SIM and what baseband (firmware) do you have on your phone now???
