IPhone Tips: Force Quitting Applications
IPhone, just like other gadgets, has limited amount of memory. Although the amount of memory available in iPhone is relatively large, it will be consumed by numerous applications you run on the background for several functionalities. The operating system itself consumes internal memory substantially. After a while, several third-party applications you frequently use may seem to suffer from the lack of memory and start to feel a little laggy. You can easily solve this problem by freeing up some of the available memory; simply force some of the running applications, such as email or Safari, to quit to get more internal memory.
With the older version of iPhone, force quitting background apps can be done by simply pressing and holding the home button for 6 seconds. This will kill the application and the background process as well as take you back to the home screen. With newer 3.0 version iPhone, holding down the home button will only activate Voice Control on the iPhone 3GS.
If you are using newer iPhone versions, you can still force applications to quit by using the combination of sleep/wake button and the home button. Simply hold the sleep/wake button until the slide to power off screen appears, and continue with holding the home button until the application quits. Now that you know how to force background applications to quit and free up some memory space, you can easily run memory-intensive applications such as Teleport without hassle. No more lowered performance or lack of memory issues by using this simple trick.
