Since iOS 4.0 iPhone supports "multitasking" this means if you click the home button your app sleeps, this needs almost no battery or memory and if the iPhone run out of memory it will terminate sleeping applications.

Every app supports this kind of multitasking exepted you don't allow it for your app.

But there are also three real multitasking functions:

• VoIP
• GPS
• Music

Those three functions you can really use for multitasking apps. But nothing more...

Your application will move to background,if your iPhone device support multitasking feature, you can select and bring that in foreground, And multitasking is supported in iOS 4.0 and onward.

So for the iOS 3.0 and below, when you click on the Home button then your application is automatically terminated my iOS itself.
