I have a 9530 unlocked and running on ATT. I like so many others am having issues with the radio. My signal strength is good most of the time, but keep not seeing EDGE, and when I do, it doesn't seem able to stay locked on it. I am running 132 straight up.

I was thinking I would try the swap a radio but can not seem to find the older os or radio files. Or should I try one of the hybrids?

Any help or links would be greatly appreciated.
