Been using IOS7 for a couple of weeks now, going back to IOS6 is really weird now. The only thing I hate is the built in Music app, it's a complete mess and is terrible to use, so much so that I found an old ipod to use in my car instead of even trying to find the music I want to listen to. Albums and Artists lists that show up perfectly in itunes are jumbled all over the place once copied over to the phone, for example having every tune on a compilation album in it's own album with 1 song in it, but in itunes it's perfect.
