And I believe I may know why. There are several software and firmware versions of Cingular's incarnation of Treo 650. There are "orange" and "blue" versions, for "Cingular" and "AT&T". Merging these networks went less than seamless., and your phone does not give you a choice of "blue" and "orange" networks. I know it sounds confusing, but in some parts of the country I can see 2 separate "Cingular" entries as available networks.
I would venture a guess that your phone was purchased locked to Cingular, and has a "CNG" version vs. "CNB". By going to "Options" and selecting "Phone Info", you should be able to see your software version. Mine is Treo650-1.17-CNB.
