Yes! I know that for a fact but it changed.
Something popped up after I logged in my old app world account in my laptop then all of a sudden, the new bb pin was changed to my old pin! And now the bbm is not working. I'm so annoyed! I know that this is not possible but it's true. I've been searching for solutions over the net and yet, I found nothing. If only someone knows how to reset the blackberry device pin to the original. I'm still hoping!!!
