Looks like they added some "buttons" for us, too! Hey! Maybe I will be able to move from iOS 6 to iOS 7.1. THANK YOU for letting us know about the changes.
I rolled iOS 7 back to iOS 6 the day after it was released because I wasn't able to use my phone effectively anymore. (A teenage computer guru helped me restore my phone before Apple stopped "signing' iOS 6 - whatever that means!)
Here is a page with screenshots of the new iOS 7.1. I think this might work for me. I hope to meet up with some friends who have this update and who will let me play with their phone for a few minutes. If I can see it, I'll update to the new iOS 7.1.
This page of YouTube videos showing the screenshots is really helpful: http://9to5mac.com/2014/03/10/new-in-ios-7-1-big-iphone-4-performance-improvemen ts-better-navigation-audio-and-more-videos//
