title: iOS Development: How can I run my iPhone 4.2 app on the iPhone 3.2 simulator?
body: <p>I'm diving into iOS development and I'm building a simple app that will support iOS version 3.2 to 4.2.  I've tested it fairly well in the latest version of Xcode on the 4.2 simulator, but I would like to also simulate it running on a iOS 3.2 device.  After reading a few tutorials on this, I managed to download and install an older version of xcode along with the older 3.2 SDK, but when I build my project in the older version of Xcode, I get a ton errors due surrounding all the iOS 4.2 functionality that the older version of Xcode doesn't support.  I'm weak-linking all the 4.2 frameworks, but I'm still getting errors.  How can I get my 4.2 app to build successfully in this older version of Xcode and get it to run in the 3.2 iPhone simulator?</p>
  
  <p>Thanks so much for your wisdom!</p>
