title: Can I use the new Xcode 4.2 Developer Preview to publish regular apps now?
body: <p>Making the long story short: if I download and install the new Xcode 4.2 Developer Preview on my Mac and start developing new iOS 5 apps, can I still using it for developing and releasing iOS 4.x apps?</p>
  
  <p>I do not have the possibility to install two different versions of this platform right now.
  Probably someone amongst you has tried it and can answer.</p>
  
  <p>The <a href="http://developer.apple.com/library/prerelease/ios/#releasenotes/General/RN-iOSSDK-5/index.html" rel="noreferrer">iOS 5 beta Release Notes</a> link associated to the new Xcode version seems to be broken.</p>
  
  <p>Thank you!</p>
