Am using SDK 4.2 and when I run the Hello World program from the downloaded code I get an error - 'Check dependencies: there is no SDK with name or path 'iphoneos3.2' Where is this code located so that I may be able to change it and continue to compile correctly?

Open the project in Xcode, in the Groups & Files Column select the HelloWorld group (single click). Use Command-I to "Get Info". In the Build tab, under Architectures you will see Base SDK. Change the Value of iOS SDKs to
Latest iOS (currently set to iOS 4.2)
Quit Xcode and restart... It should now Build and Run successfully.
