Packaging AIR application inside IntelliJ vs ant build configurations

Hi all,

I am using the IntelliJIDEA 12 to develop an Adobe AIR iOS app.

I find that using the Build -> Package AIR Application for ad hoc distribution, the ipa that I get works on my iPod

However, when I use my ant build, the ipa gets stuck on the splash screen.

I am using Flex SDK 4.6 with Adobe Air 3.5 and I'm testing on iOS 6.

Any ideas on how or where to dig deeper on this issue?

Don't know where to start

Thanks!
