Installed 6.7.2233 and it was pretty flawless. I flashed back to .902 and did an OTA update to .905. I haven't rooted yet but I hear there is a way to do it.
Couple of things I noticed
On stock launcher, when plugging in webtop it doesn't work. I got ADW and it works fine now.
Bluetooth seems to work better, wifi is WAY faster (I know this by doing speed tests a lot before and after). I can't speak for 4G yet but will report back when I know for sure how it's doing.
CPU is now running at 1200MHz vice 1000 and it doesn't seem that it auto adjusts to lower speeds like previous versions did so we will see how battery life does. Battery life seems fine so far though.
