ios6 - Xcode 4.5 callStackSymbol not Symbolicated

Question

I am using NSException's callStackSymbol to log the stack trace of my crash and send it to my server.

I am getting this kind of stack trace from my release ipa file and/or the original released app on iTunes.

And I'm getting this on debug/release via Simulator (I was getting this kind of stack trace before supporting iOS 6.0):

13  MyApp                               0x000deaf0 [MyApp start] + 10992

My question is, what should I do to make it symbolicated (do not offer me of using symbolicating tools because it was working on the previous releases and supporting iOS 6 using Xcode 4.5, it became like this, and it is not iTunes.crash file).

If there's any chance of getting the reason of the crash from iTunes.crash, can you teach me how to do it? I searched for about 6 hours and I still didn't find any clue.

Thanks in advance!
