Yep, the flashlight app uses both the LEDs on the back and has 3 different brightness settings. Only thing I wish it had was a widget.
First impressions is that due to Sense, the only real change with Froyo that we'll notice is the speed difference. Most of what I'm seeing are changes HTC made with Sense. (Which I'm not complaining, I've liked what HTC has done with Sense/TouchFlo since I first got TouchFlo 2D working on my Apache)
The on screen keyboard is also slightly different. It has the same look, but it now has the .com key in portrait, and they ditched the key to hide the keyboard.
Something I don't like is all the junk that is included: Amazon MP3, City ID is still on there, and they added VZ Navigator.
You still can't disable Sense, unless I'm just looking past it.
My battery life has not been great, but I have hardly put the phone down this morning. (On a side note: Stocks and news were set up automatically in sync at some ridiculous auto update intervals. 4 hours for stocks and 1 hour for news if I remember correctly. I killed stocks and set news to manual)
On my way to grab breakfast this morning I shot a video. The color is off because I jammed the phone between the mirror and the headliner, not paying attention to the tint strip at the top of the windshield. It's a long boring, blue tinted video, but it at least shows the framerate isn't too bad. I'll try to do something better this afternoon.
