Very stuck on a really wierd problem with ADT and native extensions on iOS

So I am using the native extension from http://blog.aboutme.be/2011/12/10/udp-in-air-for-ios-using-a-native-extension/

It comes with a flex demo app that works perfectly on Android and iOS when built in FB. I made a small as3 app in FB and that works perfect on Android and iOS as well.

I then took the app.xml from the as3 FB project and used it for my flash pro/adt project. I built the package in adt with the following

Android:

start adt -package -target apk -storetype pkcs12 -keystore androidTest.p12 NetPRO_Demo.apk NetPRO_Demo-app.xml NetPRO_Demo.swf 72icon.png -extdir extensions

iOS:

start adt -package -target ipa-ad-hoc -storetype pkcs12 -keystore Certificates.p12 -provisioning-profile CashRegisteriPad1.mobileprovision NetPRO_Demo.ipa NetPRO_Demo-app.xml NetPRO_Demo.swf 72icon.png -extdir extensions

The Android version works perfectly, the iOS version sits at a black screen and freezes. I have spent days on this, what is wrong in my ADT packaging that is different from FB packaging that it breaks only on iOS.

Also, if I get rid of native extensions, my ADT packaging works fine.
