Nokia has just announced a new firmware for its flagship N-Series handset, the N97. The new firmware version 21.0.045 brings with it quite a few changes (for the better) and primarily improves the call quality and the overall Internet browsing experience, if you happen to use the default browser. On the UI front, Kinetic Scrolling has been improved and you will see less of the jumpiness that had bee noticed with the previous firmware. The update is now available for select product codes on the Nokia Software Updater. The entire update is a 138MB download and there is no OTA (Over the Air) update available as of now. As always, make sure you take a backup of all your stuff before you update.
