Same exact thing happens with the iPhone. My belief, as an EE, and I stated this before a few times...the data bus handling all of the information appears to "mute" when the phone it's passing data through it. Email, calendar reminder, etc. all appear to have an effect on the radio. I think those getting "updates" thinking they see a slight improvement is all in your head. We all want to think it got better, but it truly has not IMPO. I don't think these "updates" are doing a damn thing to address the issues we are all discussing here. I can get my radio to do exactly what it's doing 100% of the time fairly easily. There is either a hardware/software issue or both and my thoughts/fears are that they will not be addressed until the next redesign and this will be what it will be.
