I am running it on my iPhone 5. So far enjoying it. Little things are odd though. Like my lock screen image even though sized right when I set it doesn't appear correctly. Still seems a bit laggy when going to home occassionally. Have a few apps where the menu bar at the bottom moves to a bit above bottom. Like it would if it was not optimized for iPhone 5. But the rest of the app stays the same. And missing the weather in the notification center. Especially now that the notification center is available on the lock screen. Would be super handy. Other than that it seems like a pretty good update. Glad they finally got around to adding some things that people have been wanting for awhile.
