Increased iOS app start time going from SDK 3.3 to 3.4

Hello,

I recently updated my iOS app from Air SDK 3.3 to 3.4 and I noticed that the launching time increased dramatically when packaging for ad-hoc and app store. By launching time I mean the time the app is showing only the Default.png and didn't start to execute any code. With the 3.4 SDK my app starts in approximately 14 seconds, and after downgrading to 3.3 SDK, it only take 3 seconds. Is there anything I could be missing ? Thanks for the help
