You clearly don't understand ENS, which isn't a panacea -- ENS simply allows
Cingular to "home" an ENS SIM to either the "blue" (old ATTWS) or the "orange"
(old Cingular) network in order to optimize performance in different
locations. (It's *not* just a matter of frequency -- in some locations the
blue signal will be better, and in other locations the orange signal will be
better.) ENS *doesn't* combine the two networks, and it *won't* automatically
choose a better 850 blue signal if there is a "usable" orange 1900 signal when
homed on orange. The difference in performance is thus a matter of which
network is the home network, not the frequency.

It's only "fair game" if the differences are disclosed -- lumping them
together isn't valid any more than saying that the average person has one
breast and half a penis.

Almost certainly untrue, since ENS capable handsets have only been available
for a little more than a year, and since the average subscriber keeps a
handset on average for more than two years. Perhaps half of in use handsets
are ENS capable, although only Cingular knows with any certainty.

Along with a number of other non call things, as you would know if you'd
actually read the results, including no immediate voice mail notification, and
no immediate text message notification.

It's not a "poor" showing -- what the survey actually shows is that all
carriers are roughly comparable and that all carriers have gotten better.
Differences were small, perhaps even within the range of sampling error.

Or more than that -- there's simply no way to know.

Unlikely, since D-AMPS ("TDMA") has largely been migrated to GSM, and since
coverage wasn't being surveyed. Otherwise T-Mobile (GSM 1900 only) wouldn't
have done as well as it did.

It's actually just a childish response to being shown to be wrong so often.
Eyes squeezed tight shut, hands clapped over ears, chanting over and over,
"I can't see or hear you!"

Funny and sad how you try to claim that other have your own weaknesses.
