I have a second hand Nokia 5800 XpressMusic and if I do this:

main menu (middle button) > Settings > Connectivity > Bluetooth > then press the thing to turn it on it says 'unable to perform bluetooth operation'

I cannot ask the previous about it because he was my sister's ex boyfriend and they broke up and they hate each other because he threatened my family lol. Has anyone else had this problem and if so how did you solve it?
