Yes. AT&T also announced plans to get into the next layer, UMTS, which uses
the concept of code division multiple access (CDMA), but isn't the same as
Quallcomm CDMA (IS-95/IS-2000/CDMA2000). I don't know offhand which of the
GSM-core technologies are/will be deployed by them at this time, as they
aren't the carrier I currently use.
(To my knowledge, however, AT&T does offer GPRS, which is slow, but if using
at least two timeslots, still faster than IS-95 CDMA non-1X data. 8-)
