Re:T-Mobile vs Nokia (Score 0)

YMMV. I have a Nokia 6600 phone, T-Mobile service and I hear this sound all the time. It was especially loud when I was using a Lucent headset phone at the call center I used to work in. I still hear it over my headphones (both pairs are made by Sony - one wired, one wireless). The sound isn't particularly loud over my headphones. Sure, it disrupts whatever I'm listening to when it occurs, but, like someone else mentioned, it is also an indicator that my phone is about to start ringing. For that reason, I don't really mind the noise.
