Hey AC, just to make sure because I've only used the 7130e & the 8703e, but all of the PIN's I have seen with BB are hexadecimal and your PIN only has numbers so have you confirmed you and they have your correct PIN?

One of my issues from the beginning was the person on the other end didn't have my correct PIN # so confirm that as well. Also, skimming back through your previous posts I didn't see where you had done an OS re-install which may resolve the issue.
