I can't remember my old password for my blackberry. Any one know if possible to reset. Used to be on BES but has been deactivated.

No way around it. The password cannot be recovered or bypassed.
Enter an incorrect password 10 times to wipe the device and start over.

so it will be possible to reload all the programs and use the device after I get locked out and it dumps everything?

yes, but the information and any 3rd party apps will be erased.

thanks!
