[iLiberty+] Sim card accepted but no reception

I got a new iphone 1.1.4 and unlocked with ilibertyx. I didn't click on the 3.9 tick box (but think I probably should) Anyhow, now the phone is unlocked and the sim card is recognised (or i presume it is as the phone asked me to unlock the sim), however I can't make or receive any calls on the phone.

I live in Norway and the carrier that i use here is Chess and apparantly all carriers in Norway are able to work with the unlocked iphone.

I checked the other threads and none of the relavent ones seem to have this problem.

Any ideas on how I should fix it?
:(

I had the same problem when upgrading an iPhone from 1.1.2 to 1.1.4.

I used bootNeuter to reflash the baseband and bootloader and now it works flawlessly :)

Hey Thanks for reply.

How do I do this? I'm just a bit worried about making an error and i'm new to this, but want to learn. If I do it and screw it up is it still possible for me to virginize?
