If you have many screens of apps on your iPhone or iPod touch, it can be a chore finding and launching apps you don't use often. Instead of swiping through your home screens to find an app, use this tip to get to any app, fast.
If you're in an app, press the Home button to exit the app. Press the Home button again. (If you're not already in the first home screen, this'll get you there.) Press the Home button one more time. Now, you're in the Spotlight search screen.Type the name of the app you'd like to launch. When you see the app listed in the search results, tap to launch it.
The search screen is not only great for finding apps, but also for finding contacts and songs, too.
