Tried to make a few calls this evening and kept getting the message "Radio Path Unavailable". What does that mean? does Gustav or RNC Convention have anything to do with that? LOL.

I've had the same message at times although not for about a month (knocking on wood). Even posted a message about it but didn't get much reply. Hopefully this thread brings up the discussion again.

You can try this:

Radio Path is unavailable

Also, it sounds like its a network issue rather than your phone. google "blackberry radio path unavailable" and you will find some resources.
