How to lock your bluetooth from sending files
 
 Some friends are so lousy that when they
 get hold of your phone, they would mark all the media files on your phone and start sending without your permission.
 
 Infact, that is what is happening to me
 right now, a friend marked all my 700 songs, and sending it
 via Bluetooth upon my phone is running
 out of battery.
 
 You can prevent this from happening to
 you by locking your Bluetooth.
 
 To lock your Bluetooth, simply switch it on, go to
 your homescreen and dial *#9990#
 
 Your Bluetooth has been locked, you can't
 send or receive files unless it is re-activated.
 
 To re-activate the Bluetooth, reboot the phone (switch off and switch on)!
 
 Enjoy!
