Not only Safari..I like it a lot more on a darker background, however I really hope Apple listens to the feedback and decides to change the Safari icon before releasing to the public.
I agree. I hate how some of the icons look so badly made. For example, Newstand and Camera look a little bit pixel-y if you notice in the picture, and Safari is self explanatory. So are the others you mentioned.Not only Safari..
Camera, Reminders, Stocks, Game Centre (why is this one glossy?), Newsstand, and Settings.
Please change them..I'm not updating to iOS 7 until there is a jailbreak.
