I updated my iphone 4s to the new ios 7.0. I had a lot of trouble and it took over 2 hours and a complete restore when it froze up. I finally got it and it's working correctly. The problem is that I don't like it and want to go back to my older version. The new ios 7 looks so generic with the white screen and it's very hard on the eyes. I inverted the colors but when you do this the photos are in skeletal form and you can't see anything! This new version is worse in my opinion and I would like to know how to go back to my previous version please!
