Crash on iOS6 with iTunes ipa deployment

My game runs fine on iOS6 when I deploy on the device using ‘Build and run’ using Xcode 4.5.

But when I save an .ipa using the organizer and sync with iTunes, as recommended for testing, it crashes on launch as soon as the Unity screen appears.

I uploaded to iTunes connect and they rejected it for this reason.

My player settings in Unity 3.5.3f3:

Target platform: armv7
SDK version: iOS latest
Target iOS version: 4.3

My build settings in Xcode 4.5:

Architectures: armv7
Base SDK: Latest iOS
iOS deployment target: iOS 4.3

Anybody know how I can fix this issue?

iOS 6.0 is not supported until 3.5.6f4, so please upgrade and try again.
