What type of SIM are you using?
Have you tried setting it to WCDMA Preferred in the Phone Info menu?
My D4 is on the ICS leak now, but when it was on 219 stock, using this edit allowed it to show the global network options with my T Mobile SIM inserted despite the fact that I could not get any service because of the US GSM carrier lock. I can also select the T Mobile APN and it sticks, but still no service.
If you are trying this with an ATT or T Mobile SIM in the US it will not work.
