I accidentally update from 1.02 unlocked to 1.1.2. Now, it has the new modem firmware, and I have tried to go back to 1.02 successfully, installed Installer app, BSD and Community sources.

I then used Anysim 1.2u and it just gives me the result 'anysim cannot unlock this phone'. Other things like youtube, wifi, all work, except the phone and sms.

what have i done wrong? please help!
