My iphone has deleted all my contacts (no syncing involved-just deleted all)
So today I tried opening my contacts to make a call and everytime I hit the green phone button it would just cut back to the home screen. Then the same thing happened when I tried to open text messages. I turned the phone off, then back on again and opened messages to find there was only numbers, no names. I opened contacts and there were no contacts to display. My iphone has deleted all of them, I had done nothing, no syncing, nothing involving icloud, it just did this for no apparent reason.
iPhone 3GS, iOS 6.1
