Thats where the small carries may keep some analog around since their contract could get them a part of roaming charges, or those rural customers. So some of those little guys will probably keep the towers up as long as they can get a small profit from them. But thats the reason I'm dropping analog myself, no gaurentee that it will work. In a power outage for example, the large carriers drive a gnerator around to their remote sites to charge the batteries and keep things working but the little guys may not have that, theirs may go down once the batteries run down.
