It just released yesterday night, so not all countries got the OTA ( Over-the-air) update. The NSU Update is 140MB, but it is definitely worth it.

The best improvement was the Kinetic Scrolling and thank God no Flash flooding in my images. I stopped using my N97 for photos cos of this

( If you dont have an idea what the flash flood with N97 was, heres a link >http://carltone65.files.wordpress.com/2009/08/23062009146.jpg )
