Why? I'm regularly in areas with only Edge coverage...will the iOS5 magically switch to Edge when I have no wifi or 3g? Is there some hidden setting that will let me turn off 3g when it and my wifi connection at work bogs down so bad that I can't stream audio during peak times? Which happens daily at my workplace, forcing me to switch to Edge. So far things were going great with my shiny new 4s until I learned this. Yeah, I get that Edge will be dying but in some areas it's still the only real option, what the heck? Sorry if this is a repost.
