After upgrading to 1.1.2, you will need to restore the baseband to 03.14.02 before you will get service again. If you have wi-fi, there is a 'downgrade baseband' tool that will do the hard work for you

To get carrier signal again follow this guide exactly and your problem will be solved:

Just remember after the second software restore the next time you connect you phone to itunes set it up as a new phone or the problem will return.

Hope this works for you...
