For the carrier bundle you can use iFile (need jailbreak) and go to /system/library/carrier bundles/iphone and rename/backup the bundle of the originial carrier of your iphone - copy the name of the bundle, you'll need it later. next find the bundle of your SIM carrier and rename it to bundle of the phone carrier that you copied previously.
After that just reboot. You can check in settings>general>info that your carrier will show the carrier of the bundle renamed. NOTE: do NOT update the carrier settings in that screen.
