Just like DeleteTitle, Using CNANDContentManager is overkill, inefficient and useless. And it results in a few failures in situations where a delete should just always work. But here it gets bonus points, because it manages to actually use the TMD for deleting contents, when IOS does none of that and just deletes files ending with .app in the title content directory. :)
