Put your two fingers on the screen and spread them apart. Or you can tap two times. On the screen.

When on video, pinch the screen and the zoom line appears at the bottom of the frame.

Updated iPhone iOS 6.0 and it deleted All MY CONTACTS I do not have anything stored on icloud. Now, I do have all my stuff stored to my computer on iTunes, i just tried to restore my iPhone, but my contacts are not there. I'm very frustrated and mad that this happened.
My itunes says it hasn't updated een though I updated it? I went to update my iphone and it said I had to update my itunes first and restart my computer (i have a macbook.) So I did all that and went to try and update my phone again and it still said I had to update my itunes first so I did it again and it is still not allowing me to update my iphone. It still says I need the latest version of itunes. What am I do wrong!
My iPhone 4s was jailbroken and I updated to the ios 6? I had no idea that my iPhone was jailbroken since I bought it from my dad's friend and now it's stuck in recovery mode and I tried iTunes to restore it but it won't work what do I do?
