    I am in bayarea.
    I have had AT&T GSM for over an year on my T226. I could go to
    Connect->GSM Networks, and the phone would show the available
    networks. I get AT&T, Cingular and sometimes Tmobile networks listed
    in the available NW list.
    I get excellent signal strength at both home and inside office bulding
    with my AT&T GSM. Note that T226 works in GSM 850 and GSM 1900

    Recently I bought T637 and signed up with Cingular. But the reception
    has gone down considerably with this new device + service. My
    understanding is that AT&T and Cingular share the same network for GSM
    and the signal strength should be the same. Why is there a difference?

    Also, unlike in T226, I am not able to see the available neworks with
    my T637. In T637, if I go to Connect->GSM Networks I only see an empty
    list. There is not even an entry for Cingular!
    With the T226, I had the flexibility to switch between Cingular and
    AT&T and pick the one with the better signal in a particular area..
    and this seems to be missing in T637! Is there any way to enable it?
    Or Is there something fishy happening here?

    Btw, I got the Cingular phone from Amazon unlocked.

    thanks,
    driz

    Have you performed a "New Search" ?

    Because that's not correct -- Cingular shares network infrastructure with
    T-Mobile, not ATTWS.

    Not if Cingular has blocked it in the SIM.

    You assumed incorrectly. cingular and AT&T Wireless *will* be one
    network at some future time. They are not completely united yet.

    cingular has disabled the ability to see other networks on their
    phones.

    There is no option to do a "new search"...

    Both my previous SE phones (T226 and T68i) had it..

    ??? My AT&T GSM phones read either AT&T or Cingular, *never* T-Mobile. I'm
    in the San Francisco Bay Area, which may make a difference? The phones (an
    SE 226 and T68i) don't seem to care which, they just grab onto whichever has
    the strongest signal. Never a roaming charge.

    That's because you're an ATTWS subscriber, and ATTWS now has free *roaming* on
    Cingular. But that Cingular network is shared with T-Mobile -- you just see
    Cingular and not T-Mobile because ATTWS has roaming in that area on the
    former, but not the latter, although it's the same network infrastructure in
    either case.

    If you were a Cingular subscriber, you would be sharing the same network
    infrastructure with T-Mobile, even though you wouldn't see the T-Mobile name
    since Cingular has blocked roaming on T-Mobile, which makes sense because it's
    the same network. You also wouldn't see ATTWS because Cingular blocks roaming
    on ATTWS.

    That's called free roaming, but still roaming nonetheless.

    In the Seattle market, ATT is who you roam to, and I have never
    seen "cingular extend" either, so things must be a bit different here.

    Bad example.

    T-Mobile has NO network infrastructure in California and piggyback off
    AT&T Wireless!

    You are absolutely *wrong.!* T-Mobile has been using cingular's GSM
    network in California and has been ever since they were sharing
    networks in New York. Once the cingular/AT&T deal goes through
    cingular is selling the network in California to T-Mobile. Why don't
    you make up some other stuff as well, eh?

    It's actually a joint venture.
