After getting the latest iOs7 upgrade, I set up a passcode on both my iphone and ipad. Later I decided I didn't want the passcode. So I disabled the passcode on my iphone. Now I can't use my ipad! It wants a passcode, and it won't take the original one that I had set up which incidentally was the same as the one for my iphone. How can I get back into my ipad. BTW, I had not synched my ipad with any computers. Any ideas as how I can get back in?
