Please excuse if this has been mentioned before. My wife has the Shine and wanted no Internet or texting on her line, when she signed up. She uses the phone for voice only. In her case, it would be better to not have 3G at all, since its better for data, and EDGE has been shown to be better for voice. Does anyone know of a way to turn off 3g, altogether on the Shine so it doesn't go to 3G, even when EDGE is weak?
