I just got a TB, and I was reading up how to root and flash rooms/kernals and all that nonsense. Coming from a rooted D1 running CM7, I'm a little experienced in flashing, but the more I read about the TB, I'm seeing a new thing being talked about flashing/changing: radios. I have a dumb question: What is a radio and how do you flash it? Does it help? Does a new radio come with the rom you flash? What radios would you recommend? Thanks!
