Systems and methods for transmitting and updating information feeds from a server to a client are provided to increase bandwidth efficiency and improve the timeliness of information feed updates. Using OMA DS protocols, the updating of RSS feeds, for example, may be performed without having to transfer an entire RSS feed. That is, in some arrangements, only the new RSS items are synchronized with a client. A server may alert the client when a new RSS item has been added to an RSS feed. A synchronization session may then be initialized between the server and the client. A client may send a synchronization alert to the server identifying the feed or feeds for which synchronization is desired. The server may respond with one or more new items corresponding to the identified feeds. RSS item identification information may further be mapped between the client and the server.
