One of Apple's last saving graces before they truly start experiencing more issues is iOS 7. The latest beta version of iOS 7, beta 4, began seeding out to developers yesterday.
iOS 7 beta 4 includes some aesthetic changes, which include a modified lock screen, and a new direction arrow that sits to the left of the "slide to unlock" text. There's also a solid bar up the top which is there to highlight the notification center. There are more visual refinements to be found throughout iOS 7 beta 4, too.
What does iTunes 11 do? Well, for starters the company have added support for iTunes Radio, which is set to compete against music streaming services such as Spotify and Pandora. Other than that, there's not much to talk about with the new version of iTunes just yet.
