I use Slacker radio as my primary audio source in the car. For the most part I'm in 3G areas and to be honest, I mostly listen to the stations I have cached so even that's not needed. The problem I have is that when I leave a 3G area I know immediately when it happens because I start hearing that horrible "Edge buzzing" as I enter an Edge service area. What I'd like to do is (by default) turn on 3G but have no Edge enabled. Is this possible? In SBSettings there's a 3G icon to toggle 3G but the Edge icon really toggles all data, not just edge. I'd like a convenient way to disable Edge, but still be able to quickly enable it again should I need to. Thoughts?
