Apple today released the fourth beta of iOS 7, which begins a number of improvements, changes, and bug fixes to the operating system, including a designed lockscreen, Notification Center improvements, an updated look for Safari’s bookmark menu, and more. iOS 7 beta 4 also brings a slew of minor interface tweaks and improvements that make the fourth version of the beta feel both faster and more polished. Our forum members have noted multiple enhancements that have been bundled into the release: Lockscreen - Slide to Unlock has been updated with a shifting highlight color and an arrow that draw attention to the area on the lockscreen. The arrow that denoted the Notification Center is now a line shape.
