I just got the update and successfully installed it even thought I had previously installed one of the earlier leaks and later reverted (FXZ'd) back to stock, and it STILL WORKED AND I KEPT ROOT!!!! I had used the Forever Root method and it worked, now all is great in the world.
I love that it seems to work for pretty much everyone so far which means this is the "real deal" update that we all have been waiting for. My main concern is the apps-to-SD option that I understand is "supposed" to be working now, although I can't seem to find it. I want to move all of my large game data folders over to my Sandisk SDcard and free up the internal space on the phone. It doesn't seem to work like it did back on Froyo. Once I figure it out I'll report back on how well it works or not, unless someone knows how and can tell us.
"HAPPY DAYS!!!" :biggrin:
