Iphone App crashes since using Air 4.0

Question

I have an APP called "Join Our Games Poker" into Itunes Store.
It was generated using Flash Builder 4.7 with Air 3.9 SDK.  But since Apple change the requirements in the store, the only way
to get an APP approved is using the Air 4.0  SDK Build 1619 or higer versions (now Im trying with Air SDK 13.0).
Now I'm trying to publish a similar APP that uses the same code that Join Our Games Poker has, but with different name and graphics.
I have to use Air 4.0  SDK Build 1619 or Air 13.0 to be able to publish it in the store.
If I run this new APP in any simulator or even directly into my Iphone 4S using the USB cable and debugging mode through Flash Builder 4.7, it works fine.
The same is true when I export a release build of this APP for Android.
But when I export a release build for Iphone Distribution or AdHoc versions, my APP runs fine for a while, but at some point it crashes. Any clue about the problem I have?  Thanks.
When I use Air 4.0, I got this log file in the Iphone 4S:

Answer 1

Yeah, we seem to be getting a similar issue with our Air app as of version 2.6.  We're trying to downgrade Air and confirm that it's just 2.6, but here is the error report from Windows 7 Event Viewer:
And Air 2.7 seems to be giving us memory leaks so we're not using that either.
