Successfully downloaded, and then it took about 15 tries to get the update to run. It would say that the update was unavailable, even though it was fully downloaded and ready to install.
I am still testing apps, but the first bug I have found is in Mail.
When I open the Mail app, it seems to freeze up every time. I am trying a reboot to see if it helps.
This is not to start a flame war, but the unlock screen and the notifications borrow from Android. (I have an Android phone and an iPad4, so please no attacks).
UPDATE: Reboot worked while I was still typing my 'please no flame' statement
