I got my new Nexus S last Thursday with the Tmo contract. I had enough if ATT.... It was working great at my home and everywhere else I took it. Then, since Saturday I haven't had service at my house. I've called them a few times and get the same answer.. "They are working on it". Now it's Tuesday and still no service. I'm getting a bit tired of calling Tmo to hear that they are working on it. If this is the service I am to expect I guess I'll have to take my great phone back to BB and find something else.
