Downgrade IOS version to V2

Is it possible to downgrade IOS version to V2 ?

After upgrading IOS version to V3, I am expecting a lot of problems:

  • not working visual feedback when I press button
  • rectangles coloring not working anymore (using regex value for blinds percentage)
  • resolution scaling not the same
  • crashing App on old iPod 2 every day

I put a lot of time in complex V2 project and now I can use it only on devices still using V2.

Sorry, it is not. You can sideload the old V2 Android APK but that is not possible for iOS.
