I'm running 2.0 beta on my pwned iPhone, and I noticed that the "locate me" feature in Google Maps does some cool stuff. First when you hit the button, you get the usual large blue circle, but it wobbles in and out. Then, it continues to search for Wi-Fi signals, and if it finds one, it will zoom in further, and the circle gets smaller. I don't think it did this in 1.1.4.
