Ok..
by the way Is there any method to get the Bluetooth radio ON/OFF status in OS V 4.0.2?
I have tried to make an API call
BluetoothSerialPort.getSerialPortInfo()
It will thrown an exception if the BT is turned off and working in some models with OS v up to 4.2.
But it will not thrown an exception even if the BT was turned OFF in BB perl with OS v 4.2.1
Any other useful method?
