Yes at&t can do voice and data but there 3g network is ridiculously slow compared to sprints evdo rev a. It has nothing to do with anyones area, its just not possible with rev a , hopefully with wimax it will be able to support high speeds and data at the sametime.

Again, not exactly.
EVDO Rev A IS 3g by loose 3g definitions. ATT's UMTS, when coupled with HSDPA and HSUPA (and faster HSDPA/HSUPA phones), under good coverage conditions, can be faster than EVDO Rev A in general. I won't get into the numbers or technical details, but my ATT HSDPA 7.2 phone runs circles around my Rev A. Sprint phone under similar coverage conditions time and again. If you're talking about EDGE or GPRS--yes they are slow--but they are not "3G".
And no, it's not just the network. The phone has to support the protocol (UMTS/HSDPA) and upload/download speeds (3.6/7.2). A GSM or TDMA phone CANNOT do simultaneous voice/data even though it is on ATT's network. So no, it's not just "all about the network".
Reprising my earlier posts, I believe we have the responsiblity to at least attempt to provide information that is as accurate as possible.
