Going by all the good things said here - I did the update earlier today, now I am running into serious freezing issues - every time it boots after a few minutes. I tried removing applications - seemed to improve then was back with a vengence.
I will now try to wipe all data and enterprise activate again.
If that does not help, Next step will be to downgrade - if I can get it to be stable enough to do the downgrade.
Every second update - I wish that I had not done it.
