    Cingular used to be 1900MHz only in Southern California, but since the
    merger with AT&T, they now have both.

    What area of SoCal uses what frequency? What is the frequency in Southern
    Orange County?

    I don't know about Southern Orange County. But in San Diego they have both
    850 and 1900MHz.

    The best way to test is to use a 'foreign' sim card that allows for network
    selection. Then test with both a 850mhz phone and a 1900-only phone. In
    San Diego, I see 2 Cingular selections with the 850MHz phone, buy i see
    only 1 Cingular selection with the 1900 only phone.

    I have heard both that AT&T has GSM on 850 and does not. What I can
    tell you is that on my 1900 phone there are 2 available signals
    Cingular orange and Cingular blue. AT&T definetely has TDMA on their
    850 but not convinced there is GSM overlayed on 850. Any Cingular or
    AT&T Engineers care to confirm?

    they do here where i live in washington..
    cingular was only 1900 but since the merge i can roam on both 1900 at&t and
    850 at&t.
    i have 3 towers to choose from in the network list.

    If both 850 and 1900 (Cingular and/or ATT) are available to a phone, which
    one will it pick? Does it favor one over the other? I am curious about
    this.

    I've not seen anything published about that, but assuming ENS, I think it
    tries to go with the best signal first, and there is probably backend load
    balancing that may make an impact.

    yes I have flashed a v600 that allows me to choose what tower im on. it
    doesn't really let me stay on the tower but you can see it in the preferred
    network list, they are displayed by the tower ids, ie 310-180. you can
    select what tower to register on but unfortunately the sim card takes over
    and moves it back if "home" is available.. even tho it has a weaker signal

    It will pick the Home network as long as there is a Home network signal;
    otherwise it will roam on the other network.

    ENS is only enabling configuration by Cingular of the Home network; i.e., it
    doesn't automatically select the better network.

    With the acquisition of AT&T's network, Cingular now uses both 850 and
    1900 MHz in SoCal. Using field test mode on my Moto V551 (see
    www.howardforums.com for info on how to do this), I can tell that when
    I'm on the Cingular Blue network (formerly AT&T) I'm on an 850 MHz
    channel, and when I'm on the Cingular Orange network (the original
    Cingular) I'm on 1900 MHz. The phone switches between the two to get
    the best signal, but where I live (West LA) it tends to prefer the
    Blue network.
