I liked the path that iOS 7 is following, and overall I like iOS7, however, it currently has issues with critical apps that I use and decided to bounce back to 6.1.4. The problem was NOT 7, but with applications that are not ready for the new APIs and methods in 7, emphasizing that is is a Beta for developers to use to terse those apps. To restore 6.1.4, I had to go to my iPhone portal in Xcode, and basically remove 7 from my iPhone 5. Once I did that and was able to restore to 6.1.4, I found that I had lost all of the data within my my data. Obviously I was able to restore the apps, but the histories and settings within the apps, such as over two months of listening history in Audible, was lost.
Just a caution
yes you can go back to 6, but at a cost.
