This is the official demonstration of Symbian Anna running on the Nokia N8 at the Nokia Connection 2011 in Singapore. I have talked about Anna a little in the past. Although it's just released, people started roumors about the next Symbian OS: Belle

Symbian Anna main features:
- Virtual portrait QWERTY for fast, one handed typing
- Split screen view while typing; so you can see message threads, webpages, contacts or email
- An easier to use and faster browser, delivering quicker page loads and improved navigation
- Refreshed Nokia Maps including simpler search, new public transportation routes and the ability to check-in to Facebook, Twitter, Foursquare or local social networks
- A feature to share your location via email and SMS (even to non-Nokia phones)
