i installed an application for the lock of my bbm .when i rebooted the device it is asking for the bbm password but my device is stuck and i could enter the password.

You need to be patient and wait more than 30 minutes for a response. This is an all volunteer forum and you need to wait for someone who has an answer to come along.

Can you please provide more information. What do you mean by "application for the lock of my bbm"?

Have you tried a battery pull?

Are you sure it's not asking you to validate your blackberry ID? In which case is not asking for a BBM password but your Blackberry ID password.

If you are referring to an application that locks your blackberry messenger, and you do not have your password could you not just uninstall the application instituting the lock?
