I forget my blacberry id nd i want to change - RIM BlackBerry Curve 8520 Smartphone

Plz specify which ID.

You cannot ...sorry.
Blacberry was DESIGNED securely. You get 10 chances then WIPE !!
BBs are very secure -- only the user created password can unlock the BB. There is no "master" or "override" password to do so...only the user created password can do so.
But, you may be in luck anyway...refer:

• KB05099 Steps to take before selling or after buying a previously owned BlackBerry smartphone

Failing the password the maximum times will initiate an on-device WIPE, which is included in those important instructions. But, the other steps within those instructions are likewise important to conduct...by both the seller and the buyer. Not properly completing ALL of the instructions risks rendering the BB not fully usable by the buyer (you).

Good luck!

go to
https://blackberryid.blackberry.com/bbid/recoverpassword?locale=ZSU%3D

insert your email and follow the instructions

To reset your password on your BlackBerry device, when you are prompted to sign in with your BlackBerry ID, click Forgot Password. Answer your security question and complete the instructions on the screen.
Once you have completed the steps above, you will receive a password reset by email.

Go to http://appworld.blackberry.com/ and select login. From there, select "forgot password". This assumes you remember the email address you registered.
