Is there any way to switch on/off bluetooth in iPhone programmatically?

In my application I want to switch on/off iPhone Bluetooth.i m using sdk 4.3..I got some idea regarding Bluetooth manager framework, but it's not working in 4.3..any ideas? or can we programmatically determine whether Bluetooth is ON/OFF?

Solution

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.

#if TARGET_IPHONE_SIMULATOR
    exit( EXIT_SUCCESS ) ;
#else
    /* this works in iOS 4.2.3 */
    Class BluetoothManager = objc_getClass( "BluetoothManager" ) ;
    id btCont = [BluetoothManager sharedInstance] ;
    [self performSelector:@selector(toggle:) withObject:btCont afterDelay:1.0f] ;
#endif
    return YES ;
}

#if TARGET_IPHONE_SIMULATOR
#else
- (void)toggle:(id)btCont
{
    BOOL currentState = [btCont enabled] ;
    [btCont setEnabled:!currentState] ;
    [btCont setPowered:!currentState] ;

}
#endif
