So I don't even know what all this Telestra talk is - anyone care to explain? All I know is that weeks into the 8700 transition with Cingular my Blackberry is still ruining my life. I'm willing to try anything - but I have no idea how to install any of this Telestra software considering I'm on a Mac. What do I do?

The carrier's name is "Telstra", and you cannot install carrier code from a Mac. The only thing you can do is sync via third party software called "PocketMac".

**EDIT** If you have an Intel Mac, use Boot Camp + XP for your BB needs. This is what I do.
