My wife's iPhone 5 just locked up and just keeps showing the big apple in middle of screen. It goes away then comes back like its in a loop. I got it to screen holding down home and power button to hook to iTunes. I downloaded latest software. Then it gets to the Verifying with Apple on iTunes and there is a apple with a line under it like its fixing to start loading it then the unknown error occurred 9. Iphone could not be restored. I've tried a few things I found on google with no luck. About ready to bust it. Its unusable the way it is.
