Do you have to be on JB to install the new radios, or is a radio a radio a radio? I'm still running ICS via AOKP (I know, I know) along with Franco's kernel because it has been so stable. I would love to be running one of the JB ROMs, but I'm trying to wait for a milestone (might not be able to wait that long tho).
I have a family member in a nursing home, and the facility has to be able to get in contact with me, so I've been hesitant to try any of the nightlies or build 1. I'm enjoying JB on my grouper, and to make my GNex feel somewhat better, I added a JB wallpaper (that's just sad).
