How to quit multitask apps on the iPhone
The release of iOS 4 brought multitasking to the iPhone and iPod touch (and the iPad in November), which is a great feature but I’ve had more than one person ask me how to quit apps that are running in the background.
You can quit these multitasked apps by double-clicking the Home button to bring up a task manager of sorts, and then tapping and holding your finger on an apps icon. You’ll then see a red icon appear in the left corner of the app icon and when you click on that the app closes.
As TheGraphicMac points out, this is kind of inappropriately hidden to the average user for no clear reason. I’ve had to show people how to use this feature a few times so hopefully it’s use is clarified a bit in future versions of iOS. [multitasking picture borrowed from The Graphic Mac]
It’s hidden because Steve Jobs said so: “In multitasking, if you see a task manager… they blew it. Users shouldn’t ever have to think about it.” Who are you to question his wisdom?

But should you quit all apps that are running in the background? I thought that the list you see are all RECENT apps, not just all RUNNING apps.
When I cleared the entire list, I had to setup my visual voicemail again, for example. Makes me think that some apps are meant to be running in the background all the time.
How about, say, Facebook? When you close that, will you still get push notifications?
Facebook has had push since before iOS4 was even released, so yes. Push is independent of the multitasking process.
Anyway, what most people don’t seem to realize is that closing apps in the background simply isn’t necessary, they’re stored in the RAM so they don’t use any CPU, nor do they waste battery life. If the iPhone/iPod runs low on RAM it’ll automatically close the last app in the menu.
