Already solved long time ago - when new version of Nokia Software Updater was released. Problem was in update software, I can update now.
I updated my nokia 6680 with software version 4.04.34.. But in standby mode settings I am unable to find activate standby command. so I am unable to view my calendar entries,unable to control music player at main screen.. Please give me an answer regarding this matter.in my older software version I got this function and it is very useful for me.
