I got the upgrade, and I love it. It's a much-needed change of style. I'm constantly just checking my iPhone just to look at it. iTunes Radio is the shit, I love that it constantly updates apps and you can have them running at multiple times (but it's not in a shitty-slow way like with Droids). I love the new dynamic wallpapers and I can't wait to be able to download them from freelance developers. The new camera functions are great, and the easiness of adjusting the brightness and flashlight are great. I'm also happy about how Do Not Disturb was given a much-needed upgrade. I also prefer Safari for iOS7 more than I prefer Chrome for the iPhone.

App Folders can hold less apps though now, I don't know what's up with that.

Just to clarify, I have the iPhone 4s. I think it's honestly faster now with iOS7.
