System and method for redirecting message attachments between a host system and a mobile data communication device

摘要

A mobile communication device (MCD) receives at least a portion of a message redirected from a messaging system over a wireless network, with the message containing a notification of an attachment. The MCD queries local attachment displayers regarding their location, electronic address and the types of attachment files that can be processed. The MCD then generates a request for the attachment, with the request containing information regarding at least one local attachment displayer.
