It has been expressed before that there should be an easy home screen applet for toggling Bluetooth....well I found the feature and WOW!!
Nokia's programmers hid it in the Status area of the home screen.
When you double tap in the status arear (upper right hand corner) a window will pop up with various information.
There is the double-line graphic which if you tap on it will bring up the Connectivity where you can then tap to toggle bluetooth on or off or even connect to WiFi.
