The iPhone 4 allows you to multitask, giving you the ability to run several applications simultaneously. As with any device, there's a drawback to leaving too many programs running at once. If you begin to notice significant slowdown while operating your iPhone, close some applications to get your device running normally. Use the phone's multitasking menu to manage and close applications.
