If all failed, downgrade to 1.0.2 with v4.02.x baseband, revirginize the phone to v3.x baseband. Upgrade again to 1.1.1 then 1.1.2 (to new v4.02.x baseband). Downgrade to 1.1.1 (or even back to 1.0.2), run AnySim1.2.1u, than restore back to 1.1.1(if from 1.0.2), run Oktoprep, UPGRADE to 1.1.2, run the "windows.bat" file to jailbreak and activate. This should unlock your phone on 1.1.2, but the SMS and phone function will not work properly as need to be customized (use iWorld) as "my" is not 1 of the 8 supported countries on iPhone.

Good luck, more detail info is in www.hackint0sh.org

If all the IMEI, CCID are missing, most probably you have corrupted your baseband. Go back to 1.0.2 and virginize it.

Go out of the house where the signal is stronger, go to Settings -> Carrier -> what do you get? Error?

Have you try other Telco provider too? how about when you restart your phone? do u still got this "no service" symptom immediately or after some time.

When you revirginize your phone at 1.0.2 (virginize to 3.14.xx bb), then upgrade to 1.1.2(new BB v4.12.x), downgrade to 1.1.1 then 1.0.2, after this, jailbreak/activate, and try to run the AnySim1.2.1. Make sure that the phone is fully unlock and function as it should be. Of coz making sure the "No service" symptoms is not there after 1 day, then attempt to move upto 1.1.1 then 1.1.2 with all the necessary steps.

Yep, 1.0.2 with 4.02.xx baseband, run Anysim 1.2.1u. The symptom is definitely a problem/corruption with the BB. What fw version and BB version you have now?
