On Nokia 6610/7210, you can navigate to calender when pressing the 4-way key right, and to new message pressing the key left.
The question: Does anyone know a appikation, that makes this possible on Nokia 6600? I know you can setup the 2 default keys for that. But it would be smarter to use the joystick, for custom commands, and save the 2 default keys for something else.
Please give me some feedback if you know a thirdpard application.
