Hey neighbor.
Mercy! What did you do--keep a journal of all that?
To get BB Weather working, CHECK disable MDS in the BBW options.
Set your APN just as you have with wap.voicestream.com, no username, no password.
Pull the battery and reboot the device. Don't power down.
You might need to completely delete Opera Mini and reinstall. Delete at Options > Advanced > Applications.
The BBWeather issue is quite documented and can be frutrated, but the instructions to work are documented here:
How do I get BB Weather to work on the 8100 / 8300 / 8800? - BlackBerryFAQ.com
i won't even comment on the AU logo theme.
Feel free, next time, to check here sometime before 48 hours has elapsed--and, perhaps, you might get in a better game of golf.
Good luck.
