I cannot get the app to work with face time on my phone. AT&T, 6.12 jailbroken. I added contacts to the app. I don't have the option of adding FaceTime, such as the instructions tell you to do. Every time I try to face time without being on Wi-Fi, I get the stupid AT&T pop-up that says I must enable FaceTime over cellular. Of course I cannot do that, because I am grandfathered in to an unlimited data plan and it would change that. Will this program just not work for me?
