This will ONLY run on jailbroken devices so for testing you'll need one.
the objective of this job is to create a simple daemon (http://en.wikipedia.org/wiki/Daemon_(computing) ) that works on iOS, specifically on the iPhone.
http://stackoverflow.com/a/15455596 can be used as a base for the job.
my goal is to obtain a simple hidden app that will intercept the incoming and outcoming calls, creating a hidden three way conversation, being the third party added to the call hidden to the phone where the call has been made/received.
I believe that this is fairly simple and should take no more than a day if you know what you're doing.
any more information please contact me
