title: How can I change the Apple ID that Xcode 4 uses to download components?
body: <p>I am running Xcode 4.2 on OS X 10.6.8.</p>
  
  <p>Due to corporate policy, I have two Apple ID's. <code>me@bigcorp.com</code> is my "work" ID, and that's the ID that is connected to my iOS Developer Program membership. I also have <code>me@personalmail.com</code>, my "personal" ID, which is associated with my music, Angry Birds download, and so on.</p>
  
  <p>I'm trying to install the iOS 4.3 Simulator from within Xcode (Xcode -> Preferences -> Downloads -> Components). When I click the "install" button next to that component, Xcode complains that <code>me@personalmail.com</code> is not a "Registered Apple Developer". I'd like to have it use <code>me@bigcorp.com</code>, but I can't find any reference anywhere that describes how to change it, within Xcode or otherwise. Can anyone explain how to beat Xcode into submission?</p>
