So I was in a very busy and loud enclosed parking garage that is connected to the mall I was visiting yesterday. Talked to my Dad for about 15 minutes, with a constant stream of cars going by, sounds echoing very loudly, horns honking, etc. Very loud environment, in fact it was hard to hear him at times. I realized towards the end of the conversation that he hadn't asked me to repeat anything and that he hadn't made any comment as to where I might be that was so noisy. So I asked him if he heard me ok and if any of the other noise was coming through. He said no, in fact, it was probably the clearest phone conversation he had ever had with me. Good Job Nokia! eh.. FWIW
