In addition to announcing the new iPad yesterday, Apple released an update to iOS. 

If you have an iPhone 4S, you'll get a few more language options for Siri. 

But our favorite feature is the new camera launcher on the lock screen.

 Before, you had to double tap the home button on the lock screen
and then tap the camera icon to launch the app.

Now you just swipe up from the camera icon. Easy.

If you haven't updated iOS yet,

just go to Settings > General > Software Update.

You'll be able to update to the new version of iOS, version 5.1.
