AIR on iOS, iPad Mini

I got an iPad Mini recently and am trying to create an IPA for iPad Mini for a game.

I used AIR for iOS 3.5.XX version of the SDK and published, but I was experiencing random crashes. One other shocker was the app regularly crashed when I went into stagewebview screen or when I was typing with virtual keyboard of iOS. Besides, the game ran for few minutes only when I compiled for iPhone 320 X 480 screensize. When I compile to Retina or iPad standard, I found it crash much earlier.

I'm doubtful if I've not set up the SDKs properly or something like that.

This is what I'm doing,

Inside Help->Manage AIR SDKs, I select AIR3.5 folder and in publish settings I use AIR for iOS 3.5.XX, publish is successful. But next time, I go into the same Manage AIR SDKs, I see the selection to be AIR 3.2. This is a bug in Flash Pro CS 6?

Any hints ?

How can I effectively debug / profile these apps ? Should I use Scout ?

PS : The game doesn't have any issues. I am able to run the same game on Android, without problems.

If this is insufficient info, please let me know..

Thanks
