When they say that Cingular an AT&T's data networks are not compatible, they may be referring to AT&T using 850MHz and Cingular using 1900MHz, but the 7290 is a quad-band phone that supports all GSM/GPRS frequencies. I suspect that the problem may be that you do not have Cingular's BlackBerry data service, which is different from their "regular" data service.
