Cant Get Into My Blackberry Curve Password Incorrect

1.  Plug you're Blackberry into your computer, you should be prompted for your password by the computer.  That should allow the lock to be reset.

--- If that fails...

2.  You can enter the wrong password 10x.  After that, you'll be prompted to enter "blackberry" to confirm and that will wipe your Blackberry.  "Wipe" means exactly what it sounds like.  All your personal data will be gone, but you can then enter a new password and start again.  But, if you've synced lately, all is not lost.
