What is true is some customers might expereince service problems in their area due to network integration. But Cingular is required to tell u that if that is the case. If Cingular does not tell u that it is not the case. If you have experienced and outage it is not due to network integration it is probably due to network upgrades. Like HSPDA and UMTS and PTT and other services . Those upgrades were going to happen even if the buyout did not take place.
