  - by user1760606

  New here guys but have got a genuine problem. I have an iPhone app that was developed using SDK4. With apple introducing the new iOS version 6, does my code need to be recompiled on the new SDK to make it compatible with version 6? Right now it crashes on iOS6. Also, do I need to do that everytime apple brings out a new version? I wonder every other app on earth already does that ?! Thanks, Raghav
