I got the update as well, it did it by itself while I was listening to music. I was wondering why it stopped and then when I look it said it was doing an update. It didn't even ask or anything apparently, I didn't notice anything different at first really but I did notice that the touch screen is more responsive now. I didn't notice until I read these posts saying that's what it was, but now that I tried it out, when I first got the phone it would only respond if I touched it with my finger tips, now I can use any part of my hand and it responds. I suppose that means they increased the sensitivity of it or something.
