How to Multi-task using iOS4 on the iPhone
Since the iOS4 upgrade, Apple introduced the ability to multi-task. This excellent feature is great for switching between applications, playing games, copy and pasting or referencing contact information.
To multitask with iOS4 on the iPhone simply double-tap the home button when an app is open (see below screenshot). This will produce a pop menu at the bottom of the screen showing your 4 most recently used apps. Clicking on each icon will load the appropriate app.

You can scroll through all open apps by scrolling (sliding/ swiping your finger) to the right or left of the screen.
To close an open application, simply press and hold on an icon. The icons will start to “dance” – similar to moving icons on your homescreen, and click on the “-” symbol that appears in the top left corner (see below screenshot). This will close the selected app.
Good lucking multi-tasking and moving around the iPhone quicker!!
