To be honest:
I feel pretty dumb asking this question, as it seems to be one of the most basic tasks...
But all my searches so far did not yield a result, so here is my problem:
I have a test build of an app I am working on, that behaves...let's say: special.
In order to find out what exactly went wrong in our test rig, I want to inspect all the files in the ipa bundle, not only those Xcode let's me download.
The question is: how am I going to do that?
The filenames in the iTunes device-backup are all hashed and a quick head -c 20 "$fileName";
over the directory listing was not very revealing, either...
Google's search results are infested with answers to the question "How do I get my stolen and cracked ipa onto a jailbroken device" and the questions I found here so far, all handle the direction from host computer to device as well.
PS:
Jailbreaking in order to ssh to the device is — of course — not an option.
