GSM radio Just to be on the safe side. I know the Droid 4 has a GSM radio (Chip) I know Verizon (B)locked it and that there is no way to enable it within the stock rom. I read in several threads that the Selfkang, Gummi and Cyanogen roms Do have a GSM option available. Before I start flashing I want to know if these options work. If I select GSM only, will I be able to really use the GSM network? Just want to be sure before I start messing things up. Better safe than sorry. I hope someone out there can help me. Surely, I can't be the only one who wants to try a GSM Sim card in a Droid 4 right?
