That sounds like a great idea, maybe you should talk to all the cell phone companies about it.
I'm not trying to knock anyone down here. If you own a microcell and it works for you then that's great, chalk it up to a nessicary evil. It's AT&T I have a problem with, but hey it's thier game and we all gotta play. I wouldn't be surprised though that after a few years go by AT&T changes thier policy on microcells or the FCC gets involved. They have been getting more and more active lately even on issues they themsleves are not sure they have authorty over.
