Okay, great. You updated iTunes to version 9.2, downloaded the iOS4 update and installed it on your iPhone 3GS. Congratulations. You now have multitasking. That’s great, but how do you use it?
It’s not hard, but the answer isn’t obvious either. So, how does it work? Well, let’s say you open the Pandora app to listen to some music. Simply clicking the “Home” button will take you back to the home screen and leave Pandora playing. If you double-click the “Home” button, the screen will grey out and show you the icons of the other apps you have installed. Touch swiping to the right will show more apps. Touch swiping to the left will take you to the apps you have running in the background (shown below). What do you do now?
