Answer 1

3.2.3 last beta did remove all other SDK's cause to many people tried publish Apps developed with the beta SDK, which will not be accepted. I guess GM is doing still the same

If you want to develop for 4.0,3.2 and 3.0 (plus 3.0,3.1,3.1.2,3.1.3) do the following

• sudo /Developer/Library/uninstall-devtools –mode=all (This will uninstall the current XCode installation)
• Then install first old XCode (3.2 final) in default folder (/Developer)
• Then install the new XCode (3.2.3 GM) in other folder (/DeveloperBeta)
• This way you will have both. And can launch xcode from either /Developer/Applications/Xcode.app or /DeveloperBeta/Applications/Xcode.app
