This has been the case already for awhile. If you have an AT&T phone and the phone can't find an AT&T signal it'll just go with a Cingular signal. The only problem here is when the AT&T signal is there but weak and you have a strong Cingular signal... the phone won't go with Cingular automatically.
To solve this problem, change the preferred network order in your phone to choose Cingular towers first, then AT&T. Then network selection will operate just as above but with the networks swapped, favoring Cingular.
The new Cingular SIMs will (do?) choose either an AT&T or Cingular tower based on which signal is stronger, which is something you can't achieve with an AT&T SIM.
