What you put on your resume depends almost entirely on the kind of job you are seeking, and the kind of company you are applying to.
If you were to apply for a software engineering position at my company, including this project would be useless at the best, and harmful at the worst. We are a business in the financial services industry that doesn't deal with iOS devices, and has high security standards. I suspect any project with the words "jailbreak" or "spoof" in it wouldn't be highly regarded here.
On the other hand, if you were applying for a software engineering position at a mobile security firm, including such a project would likely be highly desirable.
