I just installed the latest update here in India today. I must say that the touchscreen is hell of a lot more sensitive now. I was dialing a number and I did not even have to touch the screen properly to get the input through. I think there is a little less noise in the night time pictures, but I can't be sure about that. What are the changes that you noticed on your device after the update? Do you think the viewing angles have improved as Sony did say that the update aimed to tweak that issue a bit.
