The biggest change in iOS 5 is the revamped notification system and the redesigned lock screen. You get all kinds of notifications on your iOS device: new email, texts, friend requests, and more. With Notification Center, we can keep track of them all in one convenient location. Just pull down from the top of any screen to enter Notification Center. And you can see all your notifications waiting to for your action. And surprisingly Apple has included two widgets too. The Stock widget and the Weather widget. New notifications appear briefly at the top of your screen, without interrupting what you’re doing. And the Lock screen displays notifications so you can act on them with just a swipe. Notification Center is the best way to stay on top of your life’s breaking news. And It Just Works !!!
