/Item 2. I would suspect that if they made the tranistion, they would make it in most large cities fairly quickly, so your drawback would exist for a year at most. then I see three things happening. I see massive buildout of hte CDMA to support the demand and second I see the true dual mode phones come out from Mot and Nokia to support this. And third, I know AT&T won't publish the facts, but I will bet you a beer if and when we meet that more than 60% of the network is already using analog most of the time as the fallback. So raoming in analog is posible today. This delay thing could still be a drawback. If ATT has major business customers, say IBM or GM using CellularOne for its domestic roaming advantages. What would happen to them during this year? In your scenario, could ATT just keep its existing TDMA stuff and just try to free up 1.25 mhz in every major city? Still the problem might be that all of the $500 users are also the heaviest national roamers. This would mean that they couldn't switch these customers unless CDMA roaming was fairly widely available (if only for the call quality issues.) True, if 60% roam on analog now, they might be able to pull this off. Alternatively they could target the free CDMA phones to $500 customers that don't roam. I love your point on Item 3 which is basically, "why would ATT have to stop blustering once they use CDMA." I don't know why I assumed they would have to change their ways.:-) I have some questions though about Item 4 with the sprint phone. If they did this, ATT wouldn't be able to use its digital coverage on 800Mhz which is probably a greater proportion of its total digital. I think they just bought the 1900Mhz to fill in the gaps. Tom
