Hello there. I think this little arrow is most conspicuous element in beta 4. I don`t like the little arrow afore "slide to unlock". Home screen became asymmetrical. Users which used iPhone before iOS7 shouldn`t have unlock problems at all. For the new users Apple should implement some kind of "tutorial mode" like it done in the "Cut the rope" game. Once user does the action right, the tutorial tips stops showing. I think it would be nice and cool. What you think?
