I went back to the previous build, 0.423 because my phone acted very sluggish, it was not fast, and my browser was constantly showing a server busy or experiencing a problem message. I had a hard time in getting a connection..
I also couldn't see the video I ripped from a DVD for my blackberry - in all previous built it wasn't an issue, but with the latest one here, I got a green picture that comes and goes.
Lastly, somehow my wifi picks up a wifi profile that is not correct...e.g. I have a wifi profile for work but all over sudden it shows the profile of a bar that I go too and I have stored..
Not sure if ATT is having a hard weekend/day or what...but for now, we went back...because it didnt' work for me.
