Can anyone verify that you can or can't do data when roaming onto any of
t-mobiles 850mhz partner or roaming areas?  Any differences I should be
aware of?

I've called t-mobile about this 3 times and litterally got 3 different
answers.

1 - Yeah, it all works
2 - Yep, web browsing only but cant check email or anything else.
3 - Nope, we wont guarantee anything and we just dont know, so we assume no

So, I'm looking for someone that may know, or have attempted it before.

And if it matters, I'm on the t-zones or whatever they are calling it this
month (the cheap plan, only allows basic web browsing and email, all other
ports are blocked and must use proxy server for web browsing).  I also use
this in a teathered setup.

The short answer is: it depends. Roaming agreements vary with the
various carriers. Some only give us voice coverage and not GPRS, and
some give us everything.

I wouldn't be surprised if, for the most part, you only get voice.
That's the way it is with Unicel in the Northeast, and I believe it's
the same with others.

#3 is correct.  You might get features and you might not, depending upon where
you are.

GPRS does work with Dobson (wap and internet2).  Our Sony Ericsson T616
(unlocked) requires powering off and powering on to get a GPRS signal
when crossing into Dobson in Minnesota.  Voice switches over just fine.

Nothing shows up on the bill for roaming, and we have used it
(patiently) for internet access at our cabin.

Does this mean there are no data roaming charges for anyone?

I have consistently been told by t-mobile that regardless of what works and
what doesn't, I shouldn't expect to see any additional charges when I am
roaming.  The only catch to this seems to be that my t-mobile to t-mobile
minutes do not apply, so if I call another t-mobile phone, they are coming
out of the regular minutes (I asked for clarification, and the response
seems to be on evenings/weekends I'm completely unlimited, and during the
day, calling another t-mobile phone just comes out of my anytime minutes).

Just to provide more fodder for this topic, I was recently in the
Southeast (TN, to be exact) and could NOT roam on Cingular's 850
network, despite having a capable device and roaming maps that showed
we could.

T-Mobile's CSRs opened a trouble ticket and said I should update my
handheld's software, which I couldn't do since I didn't travel with my
cable or a copy of the Blackberry software. So, as of now, I'm not
sure exactly what the problem is, but it's the first time I've been
unable to roam in an area where I should have.

Not sure what part of TN you were in, but I was in Knoxville, Gatlinburg
and Pigeon Forge TN last week and was able to roam on Cingular and had
access to web and emails. At first I didn't have coverage, but I
remembered someone recently suggested to turn the phone off, take the
battery out, put it back in, so I tried that and after I turned it back
on the phone went from zero coverage to 3-4 bars on Cingular. I also
have a Blackberry, 7105.
Now I don't know if I was on the 850 network or not, but at least I was
on a network.

I was in the western part of the state, about an hour from Jackson. I
did the battery thing and rebooted the Blackberry. Since returning
back to NY, I upgraded the operating software on the phone, which
might help the situation. But I've roamed on 850 networks before doing
that, so I suspect something was up.

Cingular's Knoxville and east network is PCS only. There's 850 MHz cellular
in
the Chattanooga area, as well as Middle and West Tennessee. There an
additional
patch of PCS only in NW TN, Dyersburg to Paris and north.

I was in upstate NY a couple of weeks ago near
Fallsberg, NY (that's about 10 miles northeest
of Monticello.

I lost coverage somewhere or another on
NYS Route 17 (soon to be interrstate , umm, something).

Anyway, _after_ having to find payphones up
there (which is another story) and meeting up
with my friends, I had the bright idea of
doing network searches. Sure enough, there
was a strong signal for Dobson Cellular
and I was able to call out on it.

Per the t-mobile map, that area is
listed as 850 mhz roaming coverage.

(My phone is a many years old Nokia 3595, and
my SIM is an ancient Omnipoint one. I don't
know if newer phones/sims will roam
automatically).

I've had to do manual searches a lot with Nokias, which I love, by the
way, regardless of the SIM age. TM officially says the age of the SIM
can make a difference, but I don't see how it technically should, as
long as there's space on it to hold the new roaming table info.

Would an original OmniPoint SIM even have memory slots
for roaming info? Remember, back then it was _only_
Omnipoint, no others...

(plus, of course, it's a pretty small one, memorywise)

I can't be positive, because I didn't come aboard until the
VoiceStream days. But they're usually made roughly the same as far as
the ability to store roaming tables and system info. The only thing
that early ones don't have are room for large address books or room to
put things used by advanced phones, like a lot of ringtones or other
downloadables.

In order to roam on Dobson, we had to replace our Voicestream SIM with
a T-Mobile.  We could not log onto Dobson's network with an old
Voicestream SIM.  So your roaming capability may be limited.
