BlackBerry is a wireless extension of your email mailbox that allows you to send, receive, forward and reply to messages at your convenience. It integrates seamlessly with your existing enterprise email account or personal email account or use the new address included with your handheld. With BlackBerry push technology, you don't need to retrieve your email. Your email finds you. No dialing-in. No initiating connections. No effort required. BlackBerry handhelds are designed to remain on and continuously connected to the wireless network, allowing you to be discreetly notified as new email arrives. BlackBerry allows you to answer email and communicate with others whenever you want. Access the critical information you need and filter the rest. The filtering engine in BlackBerry software gives you complete control over your email. Limit the number of messages you receive on the BlackBerry handheld by setting filters that monitor key words and message fields including From:, To:, Cc:, Bcc:, Subject: and message body.
