iOS 5: Unlock device by swiping Notification

By Richard Mallion
If your iOS 5 device is locked and you receive a notification, you can swipe the notification instead of the ‘Slide to Unlock’ widget, and you will be automatically directed to the related app. If you have a passcode, you’ll still be prompted to enter it.
Make sure you swipe starting from the icon on the left hand side on the notification as shown below.
