Does anyone know exactly what the deal with Sprint is in Montana, Wyoming and North Dakota? Check out the map at: http://www1.sprintpcs.com/explore/c...USER<>ATR_cartState=group&bmUID=1146883125878 I know that over the spring / summer last year, my Sprint Treo 650 worked all over Montana (Helena, Bozeman, Livingston, Billings, and areas in between). It showed a different SID, but still worked with Vision, text messaging, etc. All calls were billed as normal Sprint calls. The same thing happened in certain areas of Yellowstone National Park (Old Faithful and Grant Village) last summer, and in March in Casper, Wyoming. The added Montana coverage is shown on the state coverage map at qwestwireless.com, but the added Wyoming and North Dakota coverage is not. I know it has something to do with Western Wireless / Alltel. What exactly is happening? If this continues, it would be a great deal for Sprint customers in these three states.
