A system for supplying network content to a device, the system comprising: a first interface for communicating with a plurality of network content sources for retrieving the network content; a second interface for communicating with the device for delivering processed network content to the device; and an agent framework operatively connected to the first interface and the second interface, the agent framework operating a plurality of autonomous agents including: a plurality of content retrieval agents for retrieving the network content from the network content sources via the first interface, the content retrieval agents comprising, for each of a plurality of network content media types, at least one content retrieval agent for retrieving the network content from the network content sources corresponding to the network content media type; a content personalization agent for processing the network content and producing processed network content, wherein said processing the network content comprises formatting the network content for presentation on the device; and a content delivery agent for delivering the processed network content to a subscriber via the device via the second interface, the content delivery agent further configured to: identify an address of an originator of the network content; determine whether the originator of the network content matches an entry in a personal contact list included in user data corresponding to the subscriber and, in the affirmative, transmit at least one tag to the device, the at least one tag identifying the originator address, wherein the at least one tag enables the device to initiate a voice or textual response to the processed network content or enables the device to initiate a transactional service in response to the processed network content. a first interface for communicating with a plurality of network content sources for retrieving the network content;
