Snow Leopard installation frees up a ton of disk space
Approximately 17 GB in my case. Not too shabby. Now I have to get Xcode 3.2 and the iPhone SDK add-on installed. BTW, the iPhone SDK installation now expects Xcode 3.2 to be previously installed, so make sure you've installed it off the Snow Leopard distribution. The 404 MB file size of the iPhone 3.0 SDK for Snow Leopard should be tip off if you've installed previous iPhone SDKs.
