In working in the communications industry, I do have to say that with ALL carriers there will be problems. No one network is perfect all the time. BUT what I will say is that I have few dropped calls and no extended network outages. When compared to my friends who have other carriers, I always have the best signal, and many times I am the only one with ANY signal. (I am in the western Washington area) I also have to say whenever there is a new phone out that catches my eye, it always seems to be available with Cingular. I have also had Sprint and T-mobile in the past and I have to say, that although they all were pretty complicated, my Cingular bill is the least confusing, and when puzzled, a rep was always more than happy to break it down with me.
