Using email to transport data
You can use the BlackBerry® APIs to create aBlackBerry® Java® Application that uses email as a transport mechanism for sending and receiving data. Email can be an effective way to proactively distribute content to BlackBerry device users if the traditional push models are not available. A BlackBerry Java Application can use the BlackBerry APIs to send email messages and listen for inbound email messages. A BlackBerry Java Application can also access the details and headers of email messages that are stored locally on the BlackBerry device and register listeners for changes in the status of an email message.
