My iPhone4 keyboard won't work anymore since I updated to ios7. I can't get a new iPhone 5S as they are sold out. How do I go back to the previous operating system?
The keyboard of my Iphone 4 won't work since I updated to ios7. I've tried to purchase the new Iphone 5S, but they are sold out for the next month. Is there a way to go back to the old operating system so I'm not without a phone for a month?
