it's the difference between the normal pin-code and the emergency puk-code. But I don't have a razr, not even a motorola. But as far as I know, it's rather standard. See http://www.mobiledia.com/glossary/199.html
Read the manual. And find the puk that came with the phone!
i have a razr v3 and i can't turn it on. my sister changed the code to turn the phone on and she forgets what it was changed to. t-mobile is the ptovider.
