I am on Nextel with a BB 7100i and my friend is on TMO with a BB Pearl. We tried to add each other in via the BB messenger, we both are on data plans too. But it just stays pending forever. The email notifications say accept and we do, but then it says bad pin or wrong passcode. But neither of us have entered passcodes or pins. We even turned this feature on and off but both times no difference.

Is this because we are on different carriers? Or what are we missing?
