So far, I have done the following:
Make and receive phone calls
Send & receive txts
Download from the market
Set up my wi-fi connection
Surf the internet
Just tried Sprint Nascar App, that works as well!!
I HAVE NOT HAD ANY PROBLEMS AT ALL! Also, I can pinch in from the sides on the home screen (or any sense screen) and it goes to a circle where you can pick which scene you want. I don't know if this is pinch to zoom, but it does this.
Also, when you double click the menu button, sometimes there is like fog that moves across the home screen. Would this be considering a live wallpaper?
