Okay, so my nokia nuron phone from t mobile won't let me out of this one screen. It says "PIN code blocked. Enter PUK code." I don't know what my code is and whenever i do it its says i have 9 attempts left. If i turn my phone off and then back on it'll go back to that screen. Other than contacting my provider what else can i do!!!! Help....i love my phone and need it! Thanks.
