New feature in iOS4 - multitasking!

This is perhaps the biggest leap in the iPhone OS - multitasking. Now you can run your favorite third-party apps and switch between them instantly. You can do that by: 

1. Pressing the home button to switch away from the current app to the home screen. 
2. On the home screen, select the next app to launch.
3. Double click the home button to show a list of apps that are running concurrently.
4. From that list you can go back and forth between many apps that are already running.

The list of concurrently running apps are shown at the bottom bar

To kill off any app from the multitasking list:

1. Hold you finger on the apps icon in the multitasking bar until they start to wiggle.
2. You can swipe left and right (if you have more than 4 apps running concurrently) to look for the app that you wish to terminate.
3. Tap on the red-coloured "no entry sign" badge on the top left of the wiggling icon to close the app.
4. Press the home button once when you are finished.

The red-coloured "no-entry sign" badge located at the top-left of the icon.

There are many apps that have not been upgraded to support multitasking. You'll need to wait awhile before the app developers implement this feature in their apps. So for now, although some apps are in the multitasking bar, you may notice them restarting each time you call on them from the multitasking bar. 


At the moment I did not notice any unusual drain on my battery life nor sluggish performance of my iPhone, possibly because many apps that I have do not support multitasking yet. I shall find out in time to come...

How many apps can you multi-task before your iPhone performance starts to be sluggish?
