Unfortunately, I don't have the time and energy to maintain this project any longer. Nokia has decided not to continue its open source plattforms a while ago, this leaves me at a point, where further development of this tool seems no longer reasonable.
Because of that(and because of the unbelievable comfort of having 2month standby time instead of 10h ;-) I already sold my N900.
If anyone would like to continue development, feel free to checkout the svn and cleanup my mess of code.
