Actually there is an app you can use the front facing camera with even if the whole mobile network system shut down. Its called the camera and you press the icon on the top right. Jesus, how desperate are you to see these people anyway?
Thanks. I've always wanted to take better self-portraits.
But at the same time, I'm still interested in getting it to work. Maybe mine is broken - will find out. But if I cannot do face time calls from my house or office, then it's largely useless.
