Here's the story:
Cingular is battling the full integration of ATTWS network assets into
the Cingular system (including but not limited to towers and other
infrastructure, billing systems, et al) and it is a HUGE undertaking.
Until it is complete, there are still 2 systems: the main Cingular
(orange) system, and the subsidiary ATTWS (blue) system. Unfortunately,
your phone doesn't know that they are part of the same company, so it
will always prefer one system over the other.
Here's how the SIM will normally prefer systems:
ATTWS SIM - will prefer ATTWS (blue) system
16k or 32k Cingular SIM - will prefer Cingular (orange) system
64K Cingular SIM - this SIM can be told to prefer either system.
Of course, all customers have access to both systems, but it's just a
matter of which one will be sought for first.
