Cingular to AT and T?

I really did believe that the merging of these two huge companies was going to be very good for the reliability of my service and the availability of great new technology. I think everyone thought that this was going to be the case when the Apple iphone was made exclusive to Cingular and thus ATT. But now that we have change completely to ATT the network is suffering. I have had more trouble with missed calls and dropped calls then I ever had in the past, no matter what company I was with. I don't know if I can support this merger anymore, I will give ATT until the end of my latest service contract to figure out what is going on. If 3G technology does not turn out to be all that it is fabled to be then I am through with ATT.
