I unlocked the radio on my D2G and tested it while in Kazakhstan using a Russian Beeline SIM. Everything seemed to work well, but I forgot to test SMS. It also worked here in the US with an At&T SIM. Follow these two links for the full how-to.

I now confirm perfect sound on 2G, but no sound at all when making a call under 3G.
Does CM9 work?
Were you able to have it work in CM9?
If so did you have to radiocomm in stock and then add cm9?
After failing to get it working under CM9, I booted back into unsafe stock ROM (219)... and got the PIN prompt!
It still says that the SIM is from an unknown source, but it does connect to network.
I could dial a number without crashing the system, and send an SMS too!
I just changed the values on my Droid 4, and it booted up fine and I'm still using a Verizon SIM. Would anything change in the OS to show me that GSM was enabled without having a GSM sim?
I will be going to France in 2 weeks and I need to figure out if I can use my phone while I'm there or if I have to purchase a cell phone for the trip.
Any downsides to installing this hack? I assume this hack will be overwritten by the official ICS upgrade which has GSM enabled as part of the ICS ROM? Does anybody know whether the official droid 4 ICS Rom will force a SIM lock to only use verizon branded SIMs or can we still use other SiMS?

hey guys I just got my droid 4 to work on a gsm network with the information you provided, thx! Just one question after I reboot my phone a second time when it is not tethered to my computer any longer the gsm seems to not work any longer until I hook it back up to my computer and redo the radiocomm procedure. Is this normal or once it has been written to my phone threw radiocomm should it not have to be redone every time you restart your device?
Oh ya and 1 more thing it still says SIM card unknow everytime I unlock my screen or reboot. Is there any way to remove this warning?
This is not normal, you should only have to do it once. SOmetimes it needs a moment after boot to catch the GSM signal, though.

Updated the first post. Added the leaked ICS info. All 3g voice problems are solved with this rom. Enjoy!
Works this leaked ICS with hardware codecs for video and camera?
