Nokia's Symbian^3 might be the latest edition of Symbian, but many would say its UI is dated and just cumbersome. Does the 1.1 update, which Nokia just rolled out, change this? Unfortunately, the answer is no, since the update offers some improvements on Symbian^3 performance, but “most of the updated features are not directly visible to end users.”
Some minor tweaks include accepting request directly from email invitations and integration of maps in the email app. In addition, Nokia N8 users will get some new content. QuickOffice 6.4 editor version and three new games (titles include Need for Speed Shift, Real Golf and Galaxy on Fire) should all be on board after the update. Expectedly, it won't be a light download with that many new features, so you should follow Nokia's advice and get it on a Wi-Fi network to save on traffic. Let us know how the update worked out for you and if you can feel the optimized speed of the platform!
