Rebooting your iPhone 4 is a common task that may need to be carried out when the phone freezes, leaving you stuck and unable to restart normally. When possible, you should restart your phone rather than reboot. Rebooting, sometimes called a "hard reboot" will cut off anything you've been doing - it is imminent you will lose any unsaved data or changes.
