Dont do it!!!!
I have gotten the update and besides a minor improvement to the touch response and a slightly improved answer incoming call screen everything else doesn't make a difference. What does happen is you lose scrolling wallpapers. The launcher doesn't notify when the home-screen changes anymore so no apps can fix it. At least not as of the time of this posting. I have tried Golauncher etc. but I couldn't get it to do what I wanted, although admittedly I didn't try for very long. Any devs got any other ideas?
