Mine had some drastic changes. It showed me that the bars I had been seeing in places I frequent (eg, my house and my office) were absolutely mythical and that, in fact, I have very poor reception in these key places. I realized that already, but now I have graphical evidence. I lided it better when I was living in ignorance of the true reception.
