I knew he would be surprised but I didn’t expect this reaction!
Another update: lost619 reminded me that he didn’t know how to unlock iOS 7 because the swipe bar was missing. After I showed him he said he didn’t like it and wanted the old one back. He was fine with everything until he realized that it wasn’t a simple setting to switch back. I was using the iPad he was upset about to film this, that’s why you don’t see him using it.
Update: My son doesn’t own an iPhone or really much of anything, he’s 4. I updated my iPad with iOS 7 and he uses it when I’m not. He wasn’t upset until I told him we couldn’t go back to iOS 6. He’s a cool kid that doesn’t like change much, deal with it.
