Downgrading a 1.1.2 phone to 1.1.1 in iTunes will only downgrade the software and NOT the baseband. You are still running on 1.1.2 baseband, that is why your phone part is not working (it's been covered a million, no a billion times on here).

Run OKToPrep and upgrade back to 1.1.2, then run jailbreak for 1.1.2 to get the phone working again! How do you do this? Do a search.
