“There have been some significant UI changes to Notification Center in iOS 5 beta 2, specifically, the way notifications are handled on the Lock Screen. In beta 1, notifications would simply appear as line items, with new notifications stacking as new line items, one after the other. In beta 2, if a single notification comes in, it now gets its own, newly styled popup.”
“In both cases, you could and can drag the associated app icon to unlock and be taken directly to the app, only the appearance of the first notification has changed. I addition, Apple has added a visible “window shade” UI element, complete with a little “gripper” handle, to the lock screen, above the single notification, so you can pull down the full list of recent notifications.”
“For alarms, the change is even more striking, as the addition of the “snooze” button seemed bitsy in the beta 1 UI but is now big and bold in the beta 2 UI (see above).”
