Thanks a lot for letting know about this update. the update is not automatically notified by NIT, I had to launch the application manager and manually refresh it then only it identified the update. No issues with update, finished smoothly.
First thing I did was to check the performance of browser.

Videos:
CNN: still bad, no improvement. Choppy voice and image
Youtube: Excellent voice and image
BBC: Poor streaming but voice is a bit better than CNN
Veoh: Didn't load the image, says I need to upgrade the flash which is not possible with NIT world so easily
Google videos: Good voice and image streaming.

Page loading speed: Appears to have improved on certain (CNN) but no change on others (BBC, google)

I see quite a bit of improvement on YT and Google Videos and none or not significant in other cases.

No issue with Memo mapper
All my podcast streams have disappeared from gPodder!
All my contacts, browser bookmarks are intact.
Booting is a bit faster after second and third booting
Browser loaded slow after first booting and was OK afterwords.
I thought application loading was a bit faster now than previous. Not sure if I am right, please let me know what is your experience.
No visual improvements at all

Ok, it is time to get back to secular work
