Cingular has some very odd pricing. It you "tether" a computer the
monthly fee is $79.99. Connection via a directly connected or integral
modem is $59.99. This is for the same continuous "broadband" 3G coverage.
There are also some oddities about the data rates.
HSDPA coverage starts about 10 miles south of us and we are stuck with
EDGE at this time. We compared a new Dell laptop with an integral modem
with a laptop that was tethered to a Blackberry. Based on technical
specifications, the integral modem should have the faster data transfer.
In practical testing, however, the tethered connection provided the
faster data transfer.

Actually $59.99 for about the past year.

Actually no difference from tethering.

Unlimited:
* MEdia Max 200 $19.99
* Smartphone $19.99
* Blackberry Personal $34.99
* PDA $44.99
* PDA Blackberry $49.99
* Laptop card or tethered $59.99
Seems pretty straightforward to me.

What actually matters is the EGPRS(EDGE) Class of the mobile device.

Actual data?

Hi John,
Perhaps the local Cingular office doesn't know what they are doing, but
the prices I quoted are current and correct at least based on what the
salesman stated and what shows on a monthly bill.
I argued with them about "tether" service and was told "that is the way
it is".
One other troubling problem with Cingular has been that the broadband
repeatedly disconnected and re-connected in a fixed setting in which
there is an excellent RF signal level. We are interacting with a SQL
Server database and this lack of connection reliability is a concern.

What I posted is correct based on the Cingular website (and my own
bill).

Training of store salesdroids isn't as good as it could be. ;)

I suspect this is a device or configuration problem, not a broadband
problem -- I'm often nailed up to EGRPS(EDGE) for hours at a time. That
said, cellular data isn't a permanent connection, so your application
needs to be able to tolerate disconnections and reconnections.
Expecting otherwise is unrealistic.
