No information from this crash report:

I was beta-testing my iPhone App (not through xcode), and the app crashed. I plugged it into itunes to read the crash log, but it provides NO INFORMATION at all.

How can I make sense of this?

Well the error seems to be this

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)

This means in 80% of cases that you tried to send a message to an object that you already released. Good luck

What you're looking for is to "symbolicate" the crash log, which makes those hex addresses match up with the source code. WHen you do a build, there is a .dSYM file also created which does this mapping. Any time you release a build to the outside world, always keep the dSYM file somewhere associated with the binary so you can symbolicate the logs.

Try here for instructions on symbolication.
