I got "No Access" when I tried a 1900-only T300 in an area where
Cingular had 850 but not 1900. I assume the phone was trying to roam on
T-Mobile 1900.

Re: Cingular's new GSM network upgrade....
What part of SF are you in? I've been using SE phones for a few years
now and if your phone is unlocked, it's probably locking onto the
strongest signal (ATT) that Cingular SIMs don't allow roaming onto.
I get that with my unlocked T68m but that gets crap reception...my R520
works much better.

Not true. Generally AT&TWS has opened the door to use of all Cingular GSM
coverage, but the converse is not true. In many areas Cingular does not
allow local roaming onto AT&TWS. California is one of those markets.

I don't think so. My unlocked Sony Ericsson Z600 (tri-band world phone) works
fine on Cingular 1900, but is barred from ATTWS 1900 (red crossed circle in
Select Network), in ZIP code 94404 at least, annoying because I'm getting no
Cingular signal but a decent ATTWS signal. My SIM doesn't show ATTWS as a
Preferred Net. This might be a unique provisioning problem, but I doubt it,
since this phone has successfully received at least two OTA updates recently.
I'm checking with Cingular, but haven't gotten a meaningful response yet.

That's my understanding and experience as well. My unlocked Sony Ericsson
Z600 (tri-band world phone) works fine on Cingular 1900, but is barred from
ATTWS 1900 (red crossed circle in Select Network), in ZIP code 94404 at least,
annoying because I'm getting no Cingular signal but a decent ATTWS signal. My
SIM doesn't show ATTWS as a Preferred Net. This might be a unique
provisioning problem, but I doubt it, since this phone has successfully
received at least two OTA updates recently. (I'm checking this with Cingular,
but haven't gotten a meaningful response yet.)

Note: OTA = over the air (i.e., over the cellular network)
