Shenzhen for viewing Mobile Provision Information
Highly recommend this open source program for MACs to disply the embedded .mobileprovision Information in IPA files:
This allows you to look at how an ipa file was signed and when it expires without having to unpack the file.
It’s easy to install from a command line:
sudo gem install shenzhen
Then you can run a command like this:
ipa info MYAPP.ipa
