@zehjotkah and @RevdKathy, press the whistle button and while pressed whistle to the phone. Keep it pressed (bar should be green) and after a while it should increase. I will make a video to show you how this works (in the evening), guess it needs some works in the user-friendliness department I will fix the behaviour of quicker bar decrease when doing some activites, I just need separate counter for this. @stobbsc, it is now MaeSheep. And to resolve the conflict just run Code: apt-get update and Code: apt-get upgrade as root on your n900. The problem is with qt 4.6 libraries that need to be upgraded manually.
apt-get update
apt-get upgrade
