I'd agree with the previous comments about not waiting for faster speed
from rev A. You should realize that the speed you experience will
depend strongly upon how many other users there are on the same
tower/segment/carrier. This will also be true for rev A when it appears.
In my region there are a large number of
1xRTT (voice) towers but
perhaps only 10% of them (total of 3 in fact) also have EV-D0. Each of
those presently only has 1 carrier/sector, as far as I can tell. Unlike
1xRTT, for downstream
EV-DO each carrier is totally dedicated to a
single user. Multiple users must time share the resource. This means
that while I see as high as 1.15 Mbps down and 130 kbps for upstream
data, as soon as another user comes on the same sector, my download
speed drops to half or less so things can get quite choppy or even come
to a temporary standstill.

The measurements I made were with a Novatel S620 in my laptop and with a
spectrum analyzer for monitoring the tower. While according to
DSLReports, where I logged the tests, my result was among the highest
performance for Sprint servers, and while I performed it with an
external antenna on the card (an advantage of the Novatel, BTW)
guaranteeing good or excellent signal strength (as high as -55 dBm), it
is likely that the fact that I was careful to measure at low usage times
when there was no one else trying to use the same sector and carrier
probably trumped any differences I might have seen by using different
cards or PAM/computer combinations.
Overall I'm fairly impressed with Sprint
EV-DO performance and plans,
enough so that I just added a Treo 700P to my toybox. I hope that my
writing this doesn't encourage too many people in my area to add Power
Vision before Sprint can add enough
EV-DO carriers and towers to keep it
up! (:>)
