You really don't need to do any of that, if you select the wifi browser then you will use the wifi, it is the blackberry functions that don't work.
My contact called me last thing Friday to say it is supported by BlackBerry and he will continue to find a resolution with me on Monday. The fact that it worked whilst the BlackBerry service was being provisioned shows that it is just a config error and can be resolved. I'll keep this thread updated with the process.
