Are you a T-Mobile Customer? If you are they will help you and if they can't, they will send you to RIM in Canada. I had the same problem and RIM tech walked me though for almost 2 hours.
Have you tried a web update through Blackberry's website? that sometime will help if you can get your phone to connect.
To check for updated BlackBerry software, connect your BlackBerry to your computer to
BlackBerry - Software Updates - New Update Software for BlackBerry Smart Phones using your computerxxx8217;s Internet browser. Hopefully that will connect you to the update service and you can begin with at least the basic OS for your phone...
