Unlocking the Blackberry Curve Keypad Without a Password
1 Enter a random code into the "Lock/Unlock" screen on your Blackberry Curve. This is to be done if you can't remember and/or don't have a record of your Curve's password. A message will appear that reads "Incorrect Password".
2 Repeat the process, each time entering another incorrect password. After the tenth incorrect password is entered the internal computer will wipe the Blackberry Curve handset of all its information and unlock the keypad.
3 Clear out of the "Lock/Unlock" screen, and you are now ready to use your Curve. However, the information you had stored on the Blackberry will now be erased. An easy way to safeguard against lost Blackberry information is to backup all files on your PC (Blackberrys are only compatible with the Windows operating system) via the "Desktop Manager" program on your Blackberry Curve.
