    a. Sony Ericsson Wireless Manager 3.1.1.1220** (not Cingular software)
    b. Tested with GC82 firmware R3B9
    c. Presumably also applies to Sony Ericsson GC83 and GC85
    d. Presumably also applies to roaming on Cingular by ATTWS subscribers
    e. Tested in Northern California

    As a Cingular subscriber I occasionally find myself in a location where the
    Cingular signal is poor and the ATTWS signal is significantly better. Because
    my SIM is Homed on Cingular, and because it doesn't support ENS, normally it
    will only roam on ATTWS when there isn't a usable Cingular signal, even if the
    ATTWS signal is much better. There's nothing to be done about this with a
    handset, because Cingular programs SIMs to disable network selection.
    However, it *is* possible to force roaming on ATTWS with the GC82 (when can
    make a big difference in speed) using the Sony Ericsson Wireless Manager
    (configured properly for Cingular):

    1. Click View -> Telephony Settings
    2. Select Networks -> Current Network
    3. Wait until Retrieve (next to Get the available networks) becomes enabled;
    click on it; and then wait until Select a network is filled in
    4. Uncheck Automatically choose a network for me
    5. Select desired network
    6. Click Apply, and wait until the SIM is updated and the operation completed.
    7. Click View -> Status
    8. Check selected network and signal strength
    9. Check that GPRS appears (GPRS also appears when EDGE is available),
    and that connection is then made

    This will have to be done each time you want to make a network selection
    because the Wireless Manager defaults back to automatic selection of the Home
    network.

    ** In Global Support on the Sony Ericsson website
    <http://www.sonyericsson.com/support>:

    - GC82 and GC83 have Wireless Manager 3.0.1.1026
    - GC85 has Wireless Manager 3.1.1.1220 (plus a later driver)

    The later Wireless Manager and driver versions posted for the GC85 also
    support the GC82 (and presumably the GC83).

    Thanx John.

    Now if you could figure out some way to do this with a V400. <sigh>

    Agreed.

    EDGE throughput is much better than I expected, both on downlink (typically
    18+ KBytes/sec) and uplink (typically 12+ KBytes/sec); i.e., better than ISDN,
    good enough to be my typical means of Internet access.

    Indeed. Sony Ericsson Wireless Manager can even send and received SMS
    messages during an EDGE connection.
