my black berry has locked up no matter what button i push nothing happens I spin the wheel and the light gets bright but that is it.I have updated the BB ,I have removed the battery and did a hard reset many time but nothing seems to work.it will ring when i call it but i can not answer it because when I push the button nothing happens.What I wanted to do is wipe it clean and reinstall the os but from what I understand I need to do that from the BB not with the desktop manager.PLEASE HELP ME !!!!!!!!!!!!!!
