We don't have any hard details yet, but Computerworld reports  that Nokia's planning a busy 2011, with four to five updates to the  Symbian UI on tap, as well as dual-core phones. The information comes  courtesy of Nokia senior manager Gunther Kottzieper, who gave a  presentation at the 2010 Internation Mobile Internet Conference in  Beijing earlier today -- a slide labeled "Nokia Symbian 2011 focus  areas" indicated that a Q1 Symbian update will include over 50 features,  including a more intuitive browser, while second- and third-quarter  updates will add "a new look and feel for the user interface, a more  flexible home screen, an updatable HTML5 browser and an easier software  update experience." A hardware-related slide tipped upcoming 1GHz phones  with more graphics memory in the second or third quarter, as well as  dual-core phones and something called a "true zoom camera" in late 2011  or early 2012. (We're guessing that means an optical zoom, which would  be just wild on a mobile phone.) Ignore this morning's E7 delay and all of that sounds like evidence of renewed focus at Nokia under new management -- and it also sounds like Nokia taking over Symbian development might have lit some serious fires. We're dying to look at these slides ourselves -- we'll keep digging and let you know.
