Change the behavior of the iPhone Home button to fit your needs.
One of the very few buttons available on the iPhone is the “uber” Home button. It’s used to end applications, get to the Home screen, wake-up the iPhone, bring up the search interface and many more.
Other behaviors of the iPhone Home button include (on 3.0) includes pressing and holding it for a few seconds to get the Voice Control interface.
You can double-click the Home button to get to your Phone Favorites. What if you’d like to see the Home button do something else when you double-click it?
Of course, iPhone allows you to customize the double-click behavior of the Home button. Tap into “Settings” and then tap into “General” and then into “Home”.
On the “Home” settings page you can customize the double-click behavior of the Home button to get to the (of course) Home screen, Search interface, Phone Favorites (list of your favorite contacts), Camera or iPod.
The options are predefined so if you would have been expecting to launch a third party app by double clicking the Home button then you might have to wait for future iPhone OS releases but with the 3.0 release you have some predefined options to customize the Home button’s double-click behavior.
So, if you are an avid Camera guy you can let iPhone launch the Camera app by choosing Camera from the above options page. Or if you listen to music a lot on your iPhone then you can quickly get to the iPod feature of iPhone by choosing iPod on the above options page.
Use it at your convenience and you’ll certainly find the double-click feature of the iPhone Home button really useful.
