Cingular most certainly does have analog AMPS in the areas that they
had TDMA/AMPS or in the areas that they acquired by acquiring AT&T
Wireless. The only areas where Cingular didn't originally have AMPS
analog backup were the areas such as California/Nevada and the
Carolinas which were GSM from the outset. That's moot anyway since
Cingular absorbed AT&T Wireless and the systems that they used. AT&T
Wireless used all three technologies AMPS analog, TDMA (IS-136) and
GSM. Cingular of course is making every effort to transition all to
the "orange" side (original Cingular) and to make the "blue" side
(originally AT&T Wireless) to have all customers eventually be on the
orange side. Cingular and the former AT&T Wireless (now Cingular
blue) both use TDMA IS-136 and AMPS analog in addition to GSM.
