title: Application running on iOS4.2 but not on iOS5
body: <p>I have an application of which i have created .ipa file and tried to run the application on iOS5. If i run it on iOS 5, it works but when i try to run it on iOS4.2 it doesn't work. It opens up, shows black window and then back to home screen. I have tried things like deleting app, installing again, restarting phone, reseting it's setting.</p>
  
  <p>I know most people face vice a versa situation. Let me know if any one of you have good solution for it.</p>
  
  <p>Thank you,
  Anks</p>
