BlackBerry smart phones come with a myriad of features and options that enhance the cell phone experience, such as the option to send and receive email. Each BlackBerry also gives you the option of attaching a signature to an outgoing email. Although this feature is turned off by default, you can access the BlackBerry email options and create a signature with special characters, numbers and letters.
