Verizon has recently put up a device simulator for the BlackBerry 8703e over on the Verizon Wireless website. It is actually kind of cool if you have never used a BlackBerry before. It allows you to simulate various activities that you would perform with your BlackBerry such as composing a message, using the web browser, or sending a TXT message. It also simulates more complex tasks like creating a BlackBerry Internet Service (BIS) email account.
