Re: EV-DO?

said by Perhaps your telcos should consider joining most of the rest of the world and investing in GSM / UMTS / HSDPA technology instead of CDMA.

Economies of scale, cheaper deployments, better peer review of technologies as you actually have peers to review them, all good! Yes it does mean not keeping it in the USA by handing money to Qualcomm but surely a good thing.

Yours, with love from a 3.6Mbit/s HSDPA network.

Another ironic thing is that HSDPA uses a version of CDMA as the air interface (W-CDMA to be specific). The particular version of CDMA was not developed by Qualcomm but a number of Qualcomm patents are involved.
What is more ironic is that ATT uses GSM and NOT CDMA.

Only in the U.S.
CDMA subs = +377million, 75 million EVDO
GSM subs = +2.5 billion, +138 million UMTS/HSDPA

The ironic thing with your post is that the company playing catch up is using HSDPA. The companys with the most widely deployed EVDO are both using CDMA services.
