For those of you who are wondering how to delete or edit this signature "Sent from my BlackBerry� Smartphone" after you send an email through your Blackberry and also edit your E-Mail Home Screen icon name. This might solve it. Simply click on the Menu Button � Setup Folder � E-Mail Settings � Click on the Menu Button on your E-mail Account � Edit � Signature and E-Mail Account Name is located under the General Options drop down. Hope this helps and Good Luck!
