I went to the downloads section on the Apple Developer site but I can only see Xcode 4.2 for Lion. I need to get the version that is for Snow Leopard and will run on 32-bit. Can anyone point me to the correct place?
The last available Xcode version for Snow Leopard on dev site is Xcode 3.2.6.

You must be a registered developer with a paid account in order to download Xcode 4.2 for Snow Leopard from the apple downloads section. There is a screen shot there showing the download is available from apple if you meet these conditions.
