From the last 6 months I have been using the nokia E63 smartphone which is running with Symbian operating system. However from the past 6 months my phone is running with firmware version 501.21.001. This was also the last update in Nokia official site and after this there is no update from Nokia side till now. Yesterday I have seen my friendís E63 which he has bought 3 months back. While looking at his firmware version it was 510.21.010. How could be this possible? The Nokia official site is still showing that the last update is 501.21.001. So where I can download this new firmware?
