The iPhone holds a wide variety of data, from music files to applications. While each piece of information or program can be deleted individually, the entire phone is also reset pretty easily. Resetting an iPhone deletes all information previously saved to the device and removes the encryption key for the data. Don't reset your iPhone unless you're certain you don't need the information on it anymore because the action is permanent.
