I just tried to copy the FM radio files from my thunderbolt (couldn't find one file, hmm. ) anyway, I copied them over to my a500 running WDS' JB rom, rebooted, and it installed the radio app. When I launched it initially, I was prompted to insert my headphones so it is looking for an antenna source. I did this, and restarted the radio. This time the app launched, but is stuck at "FM Radio is being launched, please wait...".
So, what think you?
