Latest Nokia N80 firmware upgrade is available through Nokia Software Updater. Here is a simple tutorial how to upgrade a firmware. Be careful, upgrading might be quite tricky and may lead losses.

Well, there is no doubt that actual N80’s firmware(4.0707.0.7) is the very buggy as has been proven by lots of people that have been complaining about bugs with the v4 Nokia N80 firmware version which probably brings more bugs than it fixes and therefore I am so happy to say that long awaited update is finally available.
