I wonder if anyone has figured out why there is heavy audio static with OS 4.0 on the 7100t (including the latest upgrade apparently)? Everyone complained about hearing static when I had 4.0. I switched to 3.8 and it's fine.

Is the problem with 4.0 something to do with wireless syncing? Is there a conflict between the phone signal and the wireless sync signal? If so, is it possible to change a setting to stop this occurring?

It seems that RIM cannot fix the problem because it has been out there for six months. RIM doesn't even mention it. You can't call RIM directly, and T-Mobile's Blackberry representatives falsely claim that they have never heard of the problem.
