Is it possible and how to grab that information about profile just from existing *.ipa file?
I can give you a direction in this, not sure if it'll actually help:
*.ipa file to *.zip.*.app file. Open its package contents by right clicking it.embedded.mobileprovision file.EDIT- Since Xcode 6 doesn't show the provisioning profile, I'll extend the answer to still see the details:
embedded.mobileprovision to embedded.txt or just open it with any text editor of choice.Entitlements, CreationDate, ExpirationDate, Name, etc which will be sufficient to conclusively lead you to the provisioning profile used to create the .ipa.Hope it'll help!
