Ok for all you Ozzies out there I got BBweather working on the 8800.
1. Install the app and make sure you follow these help points found
HERE
2. Click
HERE to find out your Weather Location ID in Australia. The ID for Sydney is ASXX0112
3. Now I'm on BES with work so I tried both option for "Disable MDS Proxy" and they both worked with the TCP setting set to telstra.internet. It didn't work with TCP set to internet.com (as received form work) and with the "Disable MDS Proxy" ticked, I received the tunnel error. But when I un-ticked "Disable MDS Proxy" it worked.
